Fog light question

Post by AlanS »

So, my older eyes are creating an issue at night. Switched my low beams to LED H-11's, that helped. I see I have fog lights in my bumper. Never used them. Is there a way to modify these to assist in general night driving? Are they any value other than "Fog Lights"?

their throw is adjustable, so, potentially? they can be adjusted around 3 axes if they're the same as the ones on my 01 70 xc. there is also a clear lens and then a more frosted type lens, the clear ones would probably be better for this, have you had your headlamps aligned recently? that would help if it's not been done.

Auxillary light laws are state specific, so it's hard to say without knowing your location what is actually legal, if you often cross state lines you'll want to check all the states you typically travel in.

you'd get a ticket in the UK for running daytime fog lights.

Front Fog Lights are not just for driving in the fog. Generally speaking they are there to give good visibility to the near front +front/sides. This mean they are useful for driving in situations among others like on a Jeep-Road or Off-Road. They help maneuvering through rough surfaces with rocks and deep holes, etc... In other words in any situation where you need to see the details of the ground near the vehicle - and situations where the vehicle is moving rather slowly.

For this reason they are useless at highway speed - and at such speed that is what the high-beams are there for.

These low to the ground Front-Lights to be truly useful in the fog - they need to throw a light in the spectrum of Yellow/amber range. This color-range light is not only useful in the fog - but even more so - in a situation that can be described as a "white-out". A "white-out" is a term commonly used in outdoor winter sports such as skiing. For driving it involves a situation where the ground and everything else appear as white under the normal white-light of headlights. Such situation are typically in a snow storm or fog combined with snow covered roads. That is when the yellow range light helps to distinguish 'forms' within this 'white-field' such as snow banks and basically the edges of the road.
here I speak with experience as there was a point in my life where my work involved "Avalanche Control" in a ski resort. That met I had to drive in the middle of the night at every snow storm. I drove a Jeep then, and I had the big large Hella Rally style fog-lights and what a difference they made when driving in "white-out" conditions.
