Fog lights for Nissan Sunny FB15: complete selection and installation guide

Nissan Sunny FB15 is a legendary sedan that still remains popular among car enthusiasts due to its reliability and ease of maintenance. However, the standard lighting of this model does not always cope with bad weather conditions: fog, rain or snowfall can seriously impair visibility. The solution to the problem is to install **fog lights (FTL)**, which will not only improve visibility, but also add a stylish appearance to the car.

In this article we will look at everything you need to know about fog lights for Nissan Sunny FB15: from choosing the appropriate model to the nuances of connection and adjustment. You will learn which lamps are best to use (halogen, LED or xenon), how to avoid installation mistakes and why cheap Chinese PTFs can result in problems with the traffic police. And also - detailed instructions with photos and diagrams, which will help you install fog lights yourself, even if you have never tackled car electrics before.

Why is the standard lighting on the Nissan Sunny FB15 not enough?

Owners Sunny FB15 People often find that standard low-beam headlights do not penetrate fog or rain well. It's all about the design: standard optics are designed to uniformly illuminate the road under normal conditions, but when visibility deteriorates, the light is scattered and reflected from water droplets, creating a “white veil”. Fog lights solve this problem by:

• 🔹 Wide and flat light border — the PTF beam “spreads” over the road without rising upward, where the fog accumulates.
• 🔹 Yellow or white spectrum — such colors scatter less in a humid environment (yellow light with a wavelength of ~580 nm penetrates through fog 30% more efficiently than white).
• 🔹 Bottom position — fog lights are installed closer to the road, where the fog concentration is minimal.

In addition, PTFs are useful when driving along serpentines or country roads without lighting. They illuminate the side of the road and ditches, helping to avoid driving off the road. And in some countries (for example, in Europe), driving without fog lights in fog or snow is considered a traffic violation.

⚠️ Attention: In Russia, the use of PTF is permitted only in conditions of poor visibility (fog, rain, snow) or at night on unlit sections of the road. Turning on the fog lights together with the high beams is prohibited (Article 19.5 of the Administrative Code, fine 500 rubles).

Which fog lights are suitable for Nissan Sunny FB15?

There are hundreds of PTF models on the market, but not all of them are compatible with Sunny FB15. Main selection criteria:

1. Mounting type — on FB15, fog lights are installed in standard places under the bumper (if they are provided for by the design) or on universal brackets. Seat size - 120×80 mm (for most round PTFs with a diameter of 3–3.5 inches).
2. Lamp type - halogen (the most budget option), LED (brighter and more durable) or xenon (powerful light, but requires ignition units).
3. Certification - a sign is required E22 (European approval) or PCT (Russian certificate). Without this, the traffic police may fine you for non-standard lighting.

The best proven models for Sunny FB15:

Model	Lamp type	Power	Color temperature	Price (RUB)
Bosch Fog Light 12V	Halogen (H3)	55 W	3200K (yellow)	2 500–3 500
HELLA Micro DE	LED	20 W	4300K (white)	5 000–7 000
Depo 335-1101-NS	Halogen (H1)	55 W	3000K (yellow)	1 800–2 500
Morimoto XB LED	LED	24 W	5000K (cool white)	8 000–10 000

If you choose LED fog lights, pay attention to models with aluminum radiator - they dissipate heat better and last longer. Xenon PTFs require additional adjustment (so as not to blind oncoming drivers), so it is better to install them at a service center.

Connection diagram for fog lights on Nissan Sunny FB15

Connect fogs to Sunny FB15 can be done in two ways: through standard wiring (if the car is prepared by the factory) or independently by laying new wires. Let's consider both options.

Option 1: Connection via a standard connector (if available)

On some versions FB15 (for example, in the configuration SLX) there are already connectors for PTF under the bumper. To activate them:

1. Remove the lower dashboard panel (under the steering wheel).
2. Find fog light relay (usually it is signed as FOG LAMP RELAY) and check if it is installed.
3. Connect the fog light connectors to the standard wiring (wire colors: yellow - plus, black - minus).
4. Activate the PTF function via fuse No. 32 (10A) in the fuse block.

Option 2: Complete self-connection

If there is no standard wiring, you will need:

• 🔧 Relay 12V (For example, Bosch 0 332 019 150).
• 🔧 Power button (can be installed in place of the plugs on the panel).
• 🔧 Wires with a cross section of 1.5–2.5 mm² (length ~3 m).
• 🔧 Fuse 15A.

Connection diagram:

Батарея (+) → Предохранитель (15А) → Реле (контакт 30) → Кнопка → Реле (контакт 85) → Масса
Реле (контакт 87) → ПТФ (плюс)
ПТФ (минус) → Масса на кузов

Important: positive wire must go through the fuse, and minus — securely attached to the metal of the body (for example, to a bumper mounting bolt). For corrosion protection use heat shrink tube or electrical tape.

⚠️ Attention: Never connect the PTF directly to the side lights or low beam headlights! This puts additional stress on the chain and can lead to a fire. Also avoid twisting - use only soldering or terminals WAGO.

Step-by-step instructions for installing fog lights on a Nissan Sunny FB15

Installing PTF on Sunny FB15 takes 2–3 hours and does not require special skills. The main thing is to follow the instructions and take your time. Here is a step-by-step algorithm:

Step 1: Removing the bumper

To gain access to the mounting points for the fog lights, you need to remove the front bumper:

1. Unscrew 4 bottom bumper mounting bolts (under the radiator).
2. Disconnect 2 pistons on the sides (near the wheel arches).
3. Carefully pull the bumper towards you, releasing the clips.

If your model has fog grilles, they can be dismantled and used as a template for marking holes for new PTFs.

Step 2: Installing Brackets and Headlights

If you install fog lights in standard places:

1. Try the PTF on the holes in the bumper.
2. Pin them on M6 bolts with nuts (included).
3. Make sure the headlights are not loose and blocking access to the radiator.

For universal PTFs:

1. Mark the mounting points on the bumper (step back 10–15 cm from the edge).
2. Drill holes with diameter 8–10 mm.
3. Install the brackets and secure them sealant (For example, ABRO) to avoid corrosion.

Step 3: Connect and Test

After installing the headlights:

1. Connect the wires according to the diagram (see previous section).
2. Check the operation of the PTF with the ignition off and on.
3. Adjust the angle of inclination (more on this in the next section).

If the fog lights do not light up, check:

• 🔋 fuse (may burn out if short circuited).
• 🔌 Relay contacts (sometimes oxidize).
• 💡 Lamp (burnt out or poorly inserted).

Adjusting fog lights: how to avoid blinding oncoming drivers

Unadjusted PTFs blind oncoming traffic and negate all the advantages of the installation. On Nissan Sunny FB15 adjustment is made using screws on the headlight housing (usually they are located on the top and sides).

Setting algorithm:

1. Preparation: park the car on a level surface 5 meters from the wall. Load the car so that it is parked in a normal position (for example, place a load on the driver's seat).
2. Markup: on the wall draw a horizontal line at height PTF centers (usually 30–40 cm from the ground). Mark vertical lines corresponding to the centers of each headlight.
3. Adjustment:
   • Turn on the fog lights.
   • Rotate top screwso that the upper boundary of the light spot coincides with the horizontal line.
   • Rotate side screwso that the center of the spot is on a vertical line.

Critically important: the luminous flux should “creep” along the road, without rising above the level of the headlights. If the beam hits upward, you blind oncoming drivers, which can lead to an accident.

⚠️ Attention: After adjustment, check the operation of the PTF in real conditions. If the light “jumps” when driving, check the headlight mounts and shock absorbers (worn struts can change the angle of the bumper).

Common mistakes when installing fog lights and how to avoid them

Even experienced car enthusiasts sometimes make mistakes that lead to breakdowns or fines. Here are the most common:

• ❌ Incorrect connection to dimensions - leads to overload of the circuit and blown fuses. Solution: always use a separate relay.
• ❌ Installation of LED fog lights without radiators — overheating reduces the service life of lamps by 3–4 times. Solution: choose models with an aluminum body.
• ❌ Ignoring sealing — moisture gets into the headlight, causing corrosion and short circuit. Solution: use silicone sealant on the joints.
• ❌ Incorrect adjustment - blinds oncoming drivers. Solution: adjust the headlights according to the instructions above.
• ❌ Purchase of uncertified PTFs - fine 500 rubles. (Article 12.5 of the Administrative Code). Solution: check for the sign E22 or PCT.

Another typical problem is contact oxidation 1–2 years after installation. To avoid this, process all connections lithium grease (For example, LIQUI MOLY Kupfer-Spray).

What to do if the fogs fog up?

If condensation appears inside the headlight, this means that the seal is broken. Solutions:

1. Remove the headlight and dry it with a hairdryer (temperature no higher than 60°C).

2. Check the O-ring on the lamp - it may be torn.

3. Apply sealant to the housing joints.

4. If the problem recurs, replace the headlight (repair is often impractical).

Caring for fog lights: how to extend their service life

So that the fogs are on Nissan Sunny FB15 served for a long time, follow simple rules:

• 🧹 Cleaning: Wash the headlights with a soft sponge and car shampoo at least once a month. Do not use abrasives - they will scratch the plastic.
• 💡 Replacing lamps: change halogen lamps every 2–3 years (even if they are burning), since over time their brightness drops by 30–40%.
• 🔧 Checking the fasteners: After winter, check the fastening bolts - they may become loose due to vibrations.
• 🌧️ Moisture protection: If the headlight fogs up, do not turn it on until it is completely dry (moisture can cause a short circuit).

For LED fog lights additionally:

• 🔋 Check cooling radiator - if it is clogged with dirt, the lamps overheat.
• 💡 Don't touch LED chips bare hands - oil from the skin impairs heat transfer.

If you live in a region with frequent temperature changes, treat the headlight contacts WD-40 or CRC 2-26 - this will prevent oxidation.

FAQ: Answers to frequently asked questions about fog lights on the Nissan Sunny FB15

Is it possible to install fog lights on the Sunny FB15 without removing the bumper?

Technically yes, but it is extremely inconvenient. Without dismantling the bumper, you will not be able to securely attach the brackets and route the wiring. The risk of damaging clips or wiring increases 3–4 times. It's better to spend an extra 20 minutes removing the bumper than to have to redo the job later.

Which lamps are better for fog lights: halogen, LED or xenon?

Depends on budget and goals:

• 💡 Halogen - cheap, easy to replace, but fade over time.
• 🔦 LED - bright, durable, but more expensive and require good cooling.
• ⚡ Xenon - the most powerful light, but ignition units are needed, and they are more difficult to regulate.

For most owners Sunny FB15 optimal choice - LED fog lights with color temperature 4300K (white warm light).

Do I need to install an additional relay for the fog lights?

Yes, definitely! Without a relay, the load on the power button and wiring increases, which can lead to a fire. The relay costs a penny (about 100 rubles), but protects the entire circuit. The exception is if you are connecting to standard wiring where the relay is already installed.

Is it possible to drive with the fogs on during the day?

According to the Russian Federation Traffic Regulations (clause 19.4), fog lights can be used only:

• In conditions of poor visibility (fog, rain, snow).
• At night on unlit sections of the road together with low or high beam.

You can get a fine for driving with fog lights during the day for no reason. 500 rub. (Article 12.20 of the Administrative Code).

Which color of fog lights is better: yellow or white?

Yellow light (3000–3500K) penetrates fog better, as it dissipates less. White (4300–5000K) provides more natural lighting, but is less effective in bad weather. If you drive mostly around the city, choose white. For country trips in fog, yellow is optimal.
