Projectors+HID kit in fog lamps surely improves throw and brightness than stock. The projectors as compared to regular housing will provide a better spread and uniformity in lightning.

P.s- Any specific reason to stick to 4300k?

Because 4300K offers the best illumination under different weather conditions.

Not really. It depends on the type of LED . If it is blob/SMD type then it might. With the modern CSP/Flip LED's, the glare is minimal and not blinding at all. Using CSP LED's in fogs on our Tiago(4300K) and i20(5500K) and the glare is pretty minimal .

I thought the fog lamp reflectors don't have any pre defined illumination zone. They reflect the light all over the place even with a halogen bulb.
My experience says otherwise. I leave for home at about 8 pm almost everyday and see a lot of car with the LED/HID bulbs in the fog lamps. The HID completely blind everyone but the LED produce less glare. During the monsoon, the glare from the led is really high.

I don't recommend HID or LED in fog lamps at all. The best option is to go for slightly upgraded halogen lamps.
A few reasons why :
1) High foreground illumination from foglamps reduces your long distance visibility of the eyes (thats how eyes are and if the brightness is higher the pupils contract)
2) the foglamps are by design meant to throw a light till only 3-4m from the car. Even if you put high output leds , the throw will remain as long only (unless you change them to projectors , which changes the fog lamp beam to high beam, which is also a bad idea)
3) fog lamps with bulbs run at 3000k cct and that is ideal for foggy conditions - if you change them to 6500k leds, they will be useless in fog.

So my recommendation is to stick with Halogen for fog lights. If you have projectors in your main beams then you can convert them to 35W 4300k HIDs, that will give you substantial light improvement.

@MrBeast; I do not see any LED for with colour temperatures in the 2700 - 3000K range. Most are 4000K plus. Wile the rest is fine, they are definitely the best for fog applications.

Whatever you do in the name of upgrade when it comes to your car`s lighting, please be ready with a backup plan if things do not go according to your plan, if you feel even one bit unsure that the upgrade has not gone well, keep your emotions aside and please revert to stock fresh bulbs and move on, lights are very important.

(Something similar happened with a friend recently, and I had to revert everything to stock)

Fog lamps are placed too low to the ground to provide a proper beam spread for use as a main beam, even if you get them changed to a different projector set up, the height at which light source is placed matters a lot in terms of how far the beam would go.

Any projector swap must be done inside the headlamp enclosure itself, that way proper forward tilt can be maintained, this is essential to reduce glare.

Headlamps need to be placed at a certain minimum height for them to be effective, else cars like Harrier, Hector etc would have integrated the headlamp into the Fog lamp enclosure itself to improve the looks even further.

It would just make it really bright, thats about it. Oh by the way, swapping stock Fog lamp for a projector setup with super bright HID will ensure that actual Fog lamp is not there to use when needed. Its designed to be less bright & more tilted forward for a reason, it works better in actual Fog that way. Safety first!

Hello, so swapping to projectors+HID would completely ruin the purpose of fog lamps. Hence, sticking to halogen would be best? Or else adding a led with a 3000k temp would do the trick ?

LED's do not come in 3000k range. It is available only in 6500k

Okay. So 6500k means only white light. Either I switch to led or stay stock with halogen, there is in between.

I believe they provide a yellow glass cap that can make the output yellow if one desires. Mine had it but I did not use it.

Yes , stock fog lamps are better left alone.

Making the fog lamps brighter will cause more glare and not much else. A projector setup inside the headlamp or a pair of Hellas for highway driving will help. If you are on a budget a 90/100 halogen upgrade with necessary relays and wiring will work well. Just make sure you use Philips original.

Hello,
Thanks for your inputs. I do have 90/100 halogen along with the relay setup but it didn’t help much.

Yup, The yellow sticker/cap will make a yellow output and it will also cut some little light

Not entirely true, these days you can get LEDs in 3000k, 4300k as well without any film coating for it.

Agree, most people shove in a bunch of leds and light bars that light up so much area near the car that your distant vision deteriorates. Projectors installed in headlamps are the ideal option as they have foreground limiters as well to lessen the light directly near car. Projectors in fog lamps cannot have foreground limiters as they are too low. People install ultra bright lights that fill this up and keep it on always while it is supposed to be used only on low speed conditions where distance vision isn't required. eg. foggy conditions or on broken roads where you need to negotiate craters slowly.

LEDs in fogs arent that bad actually, mine arent ultra bright and cause no glare as they are the CSP chip type. They really help light up road corners and stock bulbs were useless in fogs and otherwise previously. This is ofcourse personal experience in my Grand i10 reflectors.

If possible take the vehicle to the authorized service center and align the headlights using the aiming chart for that specific vehicle. They do get misaligned after sometime. The bulbs themselves may have a life of around 200 hours.

I use stock wattage halogens , but I notice slight variations on the beam cutoff after replacing new ones sometimes(DIY), which is around 200 hours of using them, had to get them realigned and they are very effective afterwards.
