I did some search in the forum, but I would really like to know this:
If I install xenon bulbs in the OEM fog lights (I have a 1995 FD), will I have any problems with the car? Does this installation provide me with sufficient lighting of the road? Thank you in advance.

 

i have hid's on my headlights and i love them! i dunno about the fog lights.. but i wouldn't mind having them hid

 

My question is mainly about visibility with xenon in fog lights. I would like to keep traditional lamps in headlights.

 

Foglights are there for a reason.

Because when theres fog, your normal lights wont give you visibility, the foglights will, and thats why they are yellow.

If you are doing it mainly for cosmetics, then that looks good to a certain extent.

Although i hate those trucks that blind the ever living crap out of people because every single light on the front side have HIDS. Which is VERY annoying and VERY blinding for oncoming traffic, or even people they are behind of.

I think yellow fogs with the HID headlights look good anyway.

 

The fog light lens points the beam pattern down and almost 180 degree sweep. Assuming you do not melt wires or the plastic fog light body and lens you will see the road sides in extra bright white but still not see vary far down the road.

I actualy have been thinking along simlar lines of weather I couls put halagen/xeon bulbs into the '99 spec comb ligths (replacing the parking light bulb)

 

My fog lights are white and I would like to keep them white. Anyway I don't have problems with fog where I live.

 

So, if I point the fog lights slightly upwards, will I see any further down the road?

 

It depends how strong the beam is.

 

The short answer is that yes you can install any bulb in the foglights as long as they are of the same wattage (power).

Fog lights will never help you see further down the road. Your low beam and high beam headlights are focused beams, which trade width of illumination for extra range. The difference between the low and high beam is the aiming of the light, not the intensity. One of these two will give you the best visibility down road depending on speed and conditions.

Fog lights spread light near and wide. In heavy fog a focused beam gets blocked, so a fog light is designed to allow you to navigate at a slow speed and still illuminate road signs and things on the side of the road. (In good conditions you will see the signs much sooner and therefore dont' require the wide beam).

They say that yellow is a superior color for penetrating fog but I don't think white is much worse. Blue is definitely worse - don't put anything bluish in your fogs.

As a general driving tip, you should be pointing your eyes to the farthest extent that is lit by your lights. Turn on the low beams, then turn on the fogs - you'll see the fogs are only filling in between your front bumper and where the low beams first light the road. Many drivers believe more light is safer, and yes it makes you feel more secure. However, I believe using fog lights in good conditions makes drivers more dangerous because it puts the brightest light very close to the car. This causes drivers to concentrate more on the brightly lit patch right in front of the car and not look far enough out. This causes unnecessary accidents.
