How to replace PTF with FF3
So get a set of fog lights in advance, it should also have special edging, if they are not there, buy it. New PTFs come with a control unit, which must be installed in the cabin, but since you already have it, you will not need the unit. Therefore, you can go to any dismantling of vehicles and try to purchase the missing lamp there. In general, having prepared everything that you need, you can start replacing.
- First of all, open the hood of the car. Broken PTF must be dismantled by removing all glass, do it carefully. You will also need to dismantle the headlight itself. Use wrenches to remove the screws that hold the headlight. Set it aside.
- After that, it is necessary to install new (or new) fog lights. First of all, you will try to install the PTF through the engine compartment, but we hasten to warn you that this will not work for you. To install "foglights", you will have to remove the engine crankcase protection. Having done this, you can easily install the PTF in place of the old or old ones.
- When the installation is completed, the decorative ring must also be installed. From the salon, the performance of the elements is checked. It may happen that the control unit refuses to accept the new PTF, then you will have to change the second one, and then install the new unit in the car.
- If everything is in order, then only the details remain. You will need to update the on-board computer software, this is if the headlights will not turn on. Of course, you can try to do this procedure yourself, but we still recommend that you seek help from specialists. These can be masters at a service station or an authorized dealer. It is desirable that they specialize in the diagnostics and maintenance of Ford vehicles.
- After that, the entire assembly takes place in the reverse order, the headlights are installed in place. As you can see, there is nothing complicated in this process.
If you have a blown fog lamp on your Ford Focus 3, then it does not matter at all, since it is not difficult to replace it even for a novice motorist. H11 12v / 55W lamps are installed in the PTF, exactly the same as in most cars, so there should be no problems with buying lamps. In that manual, I will tell you which lamps are best to choose and how to replace them yourself.
Which lamps to choose for replacement
As a rule, Osram lamps are installed in the PTF from the factory. The cost of the original H11 12v / 55 Osram lamp is about 500 rubles and more. This lamp has an extended service life and it lasts 2-3 years. Depending on your preferences, either an identical lamp or other types can be installed in the PTF:
- Long Life Lamps
- Lamps with increased brightness +100 +150% light
- Xenon effect lamps 5000k
- LED lamps or xenon
Decide which lamps you need to shine brightly, but such lamps have less resource. To serve for a long time, but they shine worse. 5000k lamps shine with bright white light, they look beautiful, but such lamps are not visible on wet pavement.
LED lamps that illuminate the road well appeared relatively recently, but have already proven themselves. When buying high-quality LED lamps, they illuminate the road better.
Lamps with increased brightness
- DiaLUCH H11-12-55 + 90% PGJ19-2 Megalight Ultra PR from 850 rubles.
- KOITO H11-12-55 W (100 W) Other Brand price per set from 2000 rubles.
- OSRAM H11-12-55 +110% NIGHT BREAKER UNLIMITED from 1700 rubles set.
Standard Lamps
- KOITO H11-12-55 0110K from 450 rubles.
- GE H11-12-55 53110 from 490 rubles.

- OSRAM H11-12-55 + 60% SILVERSTAR 2.0 (2x resource) from 1300 rubles.
Change one lamp or two at once
Quite often they ask questions about whether to change both lamps or just one. If factory lamps are still installed, or if you previously replaced a pair of lamps at once, their resource is usually the same. If one lamp burns out, the second may burn out at intervals of a week to a month.
When buying lamps with increased brightness, they change in pairs, I think everyone understands that.
Instructions for replacing lamps in PTF Focus 3
Replacement can be done in two ways - the first way - with the removal of the lower protective apron and part of the protection. The second way is simpler - through the top with the removal of the headlight. The second method is simpler, since the headlight on Focus 3 is removed quite easily.
If changing the bulb(s) through the bottom, you will need a Torx T30 wrench and a flathead screwdriver.
The first way to replace lamps in PTF
We drive the car into a viewing hole or overpass. Using the Torx T30 sprocket wrench, unscrew the fasteners of the lower mudguard and bend it.
We carefully climb into the formed groove with our hand and turn the lamp half a turn. Disconnect the plug from the lamp and replace it with a new one.
I must say right away that it will be problematic for an inexperienced person to crawl up to the fog lamp.
The second way to replace the lamp in PTF
Using an asterisk or a flat screwdriver, unscrew the headlight mounting bolts, remove it from the grooves and disconnect the wire block.
Then, with your hand, you need to crawl up to the fog lamp and turn the burned-out lamp half a turn. Pull it up and carefully disconnect the plug.
If you install LED lamps, pay attention to the stabilizer blocks, if any. It is better to insulate them so that water does not get into them, and at the same time the contacts from the block to the lamp.
The operability of fog lights for any car is the key to its effective safety and the prevention of various emergencies on the road. Their effectiveness is especially important in conditions of reduced visibility on the road, when fog, rain or snow do not provide direct visibility. These headlights are installed under the main optics.
Important! The serviceability of fog lights must be carefully monitored, since the inoperability of this type of optics can cause an accident.
Features of the PTF device. Replacement fog lamp Ford Focus 3
Fog lights in their design are not much different from ordinary ones. Their device includes a body, a paraboloid reflector, a diffuser and a light source. To obtain the necessary visibility in bad weather conditions, it is necessary to provide good visibility, in which the upper boundary of the light beam would have maximum clarity. This means that the reflected beam, like the light from the lamp in the headlight, should not cross the horizontal plane or rise above it. Therefore, I place fog lights no higher than 25 cm above the road surface to ensure good illumination of the pavement.
Both xenon and halogen lamps can be installed as lighting elements in the PTF. Depending on the preferences of the car owner, both the first and second ones can be installed on the Ford Focus 3, as well as LED elements.
Important! Xenon headlights shine much brighter than halogen headlights, but at the same time they can blind drivers moving in the oncoming lane too much. LED lamps do not heat up and last much longer.
To make the right choice, if there is any doubt about its correctness, you can seek help from professionals who will tell you which headlights are best to install on a car.
Why is it necessary to replace the Ford Focus 3 foglight?
Since no driver is immune from changes in weather conditions, it means that it is his direct responsibility to maintain the fog lights in working condition. After all, conventional headlights will not provide the required level of illumination in conditions of poor visibility, reflected from water dust, the light from them will be scattered in the air. The main feature of fog optics is the distribution of light flux. Due to the wide and flat horizontal beam, the light spreads over the road without illuminating the curtain of fog in height. Usually, the foglights are adjusted to a short distance - about 10 meters, and the light is directed to the sides, for better visibility of the road and markings.
Important! In addition to ensuring normal visibility in bad weather conditions, this type of optics will also be effective in winding roads, when it is not always possible to notice some kind of obstacle during maneuvers.
The reasons for the failure, and, as a result, the replacement of the Ford Focus 3 PTF can be such malfunctions as: 
- Burnout of light bulbs in the headlight;
- Fuse failure;
- Loss of contact in the relay;
- Burnout of the off button;
- Weak contacts in the twist;
- Mechanical damage to the headlight housing, cracks and chips on the surface of the optics.
A malfunction of either one or both fog lights is a reason to repair or replace the necessary components or elements. This will increase traffic safety several times and reduce the risk of accidents on the road.
The self-replacement of the Ford Focus 3 foglight has some features, and if it is done incorrectly, this may affect the overall performance of the vehicle's electronics. It is better and more correct to seek help from professionals - automotive electricians who are familiar with this brand of car, have the experience and qualifications to identify and eliminate various damages in the electrical part.
Among the signs of a malfunctioning fog lamp are the following:
- The headlights don't work;
- The possibility of adjusting the PTF is violated;
- Headlights provide an insufficient area of illumination;
If at least one of the signs is detected, it is recommended to carry out diagnostic or repair work to eliminate the existing problems.
Replacement process, repair features
The process of replacing fog lights, although it seems at first glance a simple procedure, however, requires certain knowledge of both the wiring of a particular car and the features of optics. At the same time, it should be borne in mind that during the work the tightness of the headlight may be violated, the rated power of the lighting device is incorrectly selected, and if the galvanic coating of the reflector is violated, then it is no longer possible to do without a complete replacement of the headlight. It is possible to correctly and efficiently solve the problem with PTF only when contacting a car service workshop.
The replacement and repair process consists of the following steps:
- Performing the dismantling of elements that fix electrical connectors, as well as the correct removal of the radiator grille and all other fasteners;
- Dismantling of rotary mechanisms and bypass frames with removal of contacts from electrical connectors;
- Removing the headlight housing and cleaning its inner surface from dust and accumulated dirt;
- Installation of new lamps and, if necessary, sealing elements;
- Installing a new headlight and assembling the structural elements in the reverse order.
In most cases, the repair and replacement of PTF on a Ford Focus 3 car should be carried out taking into account the manufacturer's recommendations. It is in this case that their effective and long-term operation is guaranteed. Experienced auto electricians of a car service center will help you choose the necessary elements, and make their competent installation. In this case, the choice is made taking into account the following factors:
- The strength of the headlight material and its resistance to temperature extremes;
- Type and power of installed optics;
- Manufacturer;
- Compliance with a specific car model.
Important! Replacing fog lamps Ford Focus 3 requires preliminary dismantling of other elements, so it is better to entrust such work to experienced professionals.
Diagnostics and repair results
To check the performance of fog lights in modern car service workshops, there is specialized equipment that allows you to determine the cause of the malfunction as accurately as possible. Devices for scanning car electronics (testers) allow, based on the received code, to accurately find the location of the damage. At the same time, depending on the data, it is necessary to check the following elements: 
- Lamp;
- Fuse;
- Electrical circuit PTF;
- Switch;
- PTF alignment adjustment;
- Instrument panel module.
Experienced professionals, upon detection of a breakdown after diagnosis, depending on the location of the damage, will take appropriate measures to eliminate it. And if necessary, they will make a complete replacement of the fog elements, in compliance with all the necessary instructions from the manufacturer.
Proper operation of the optics is a guarantee of the safety and reliability of the vehicle, its efficient operation in all weather conditions, with limited visibility and on a winding road. Therefore, you should pay special attention to the serviceability of the fog lights of your car!
In today's publication, we will talk about self-replacing the fog lamp on the fourth generation Ford Focus. To remove the headlight from the tools, you only need a torx screwdriver and, of course, a new PTF. In my case, a spare part from the Hi-Drive manufacturer was purchased, its catalog number is FL-732.
To get to the Ford Focus PTF mount and dismantle it without problems, you must first remove the headlight. It is fastened with two torx screws, by unscrewing which you can remove the headlight housing and set it aside.
After that, with our hand we find the fog lamp cartridge below, turn it 90 degrees and take it out together with the lamp.
Now we unscrew the screws of the front fastening of the fender liner, bend it a little so that the hand crawls through, after which we take out the fog lamp housing, it is fastened with spring latches, and we install a new one in its place.
