Like I said, I followed my Defender with them on and they were fine. These days you need all the attention that you can get while driving as so many choose to multitask. I have driven with lights on, during the day, for the last 15 years. The Defender fogs (front and back) look really cool on.

Do as you please, but fog lights front and rear are only supposed to be used in limited visibility conditions. Most states have clear rules about this. For example, in California:

24602. (a) A vehicle may be equipped with not more than two red fog taillamps mounted on the rear which may be lighted, in addition to the required taillamps, only when atmospheric conditions, such as fog, rain, snow, smoke, or dust, reduce the daytime or nighttime visibility of other vehicles to less than 500 feet.

 

CALIFORNIA... full stop.

 

Never used them before but this thread made me turn them on for my zero dark thirty drive into work this morning. Definitely fully light up reflective road signs behind me on the road. So, officially too bright for anyone behind you. Different people have different tolerances for glare and dazzle when it comes to lights in the dark. You are just plain being a bad citizen if you run these all the time.

 

Yes, the most populous state in the country and the 5th biggest economy in the world. Also, one of the foggiest places in the United States along with Washington and Maine. Seems like a reasonable reference point to me.

 

My rear fog lights are 2 tiny red lights on the bumper.
They are barely visible in the day, and just another set of mild red lights at night.

Is this the same as what you guys are talking about?
