Fog lights/driving lights/switches

[ronsteward]

I hope someone with a 2002 HR Imperial can help. The fog lights are burned out. I replaced them with new ones but nothing happens. Checked with straight battery hook-up and they do come on but there is not a switch on the dash that will turn them on. My main question is, what is the 'driving lights' switch suppose to turn on. It doesn't turn on anything on mine. Is this the fog light switch? Any help is appreciated.

It might be the switch marked driving lights but they may not come on unless the headlights are on in the low beam position

It used to be that FMVSS 108 specified that auxiliary lights (fog, driving, etc.) can only be on with the headlight low beams. I'm not aware that that has changed. Of course. as the end user. you could alter the wiring to allow them to be on at other times.

Ok, I went ahead and installed the new fog lights. Then I searched the owners manual and could not anything about fog lights. So I read the owners manual again (should have it memorized soon, lol) and found that the driving lights switch is suppose to shine your headlights at 80% if you want to have your headlights on during the day. This uses less battery and makes your headlights last longer. this makes sense. However (there always seems to be a 'however' ) My driving lights switch doesn't work that way. I discovered, quite by accident, that if I have my headlights on bright, and only on bright, and turn my driving lights switch on, my fog lights come on. This does not seem right to me.
Here's my question(s) Does anyone elses work that way? Does anyone know how to get it to work like the owners manual says?
I do intend to install a separate fog light switch but the idea of running headlights at 80% during the day seems to me to be a good idea. Running fog lights and bright lights in the fog at the same time has never been a good idea for me.
