Once everything normalizes I'm going to play with some fuses and relays and I'll tell you all how to do it.

 

I did some fooling around with this today, and could not find a relay that opens to turn off the fog lights when the brights come on. I did find VERY easy way to make the fogs come on with the brights by running a single jumper wire between contacts in the box under the hood. However, the result was that the fogs came on anytime I turned on my brights. I want to have foglight control independent of high/low beam operation, so I'm going to keep digging when I have more time.

 

KEEP DIGGING!

This sound like something I may want to try.

 

Thanks for the encouragement.

 

What 2 contacts did you jump between?

 

i don't think we have a law against running fog lights even if the headlights are on high. i would like to have this feature also . and with brighter fog lights. i am in nc. i would run mine law or not. i'd rather pay a fine , than hit a deer.

 

Here's wirring for fog lamp and day time running lamps. look to me that the best way to do this is to wire in a relay after the fact. fog lamp relay so there will be no feed bact to the BCM. you can use what ever for the control for the relay like the high beam power feed at head lamp

 

I don't understand why there are laws when aux lights can be on or off. As long as there not over the 55watt legal limit, what does it matter. If its ok for these light to be on with low beam, which means when meeting other drivers, then why can't they be on with high beam which arent on when meeting other drivers? I'm glad there are no inspections were I live and its not illegal to run aux lights at any time. I have a buddy with a 4" lifted Z71 Chevy Silverado and despite my urging, he refuses to re-aim the lights down after the lift kit. We were driving behind a state trooper after dark the other night and he has his low beams and fog lights blinding the crap out of the trooper. Inside the patrol car is light up like Christmas. I just knew the officer was gonna drop behind us and pull us over. The officer turned onto another street and never paid us any attention. My 09 HHR LS did not come with fogs. I want to add the oem fog lights because I cant stand how it gets darker right in front of the car when I switch to bright. So I will be wiring mine up so the factory on/off switch will be power up when ever low or high beams are active. There are reallys with dual output pins, one normally closed, the other normally open. Its quite easy to have both low and high beam trigger a fog light relay and keep the feeds apart so low and high filiments don't get charged at same time.

Who has the best OEM fog light for sale. Fits and looks like original equipement, etc.?

 

Like the one guy posted earlier, if you have the hi and low beams on at the same time, the bulbs WILL overheat and burn out.
Fogs on with hi beams , easy to do but why? no need.

 

I don't want high and low beam on at the same time, just want control of the fog lights so I can have them on either low or high beam.

It seems the ones that design automotive headlamps decided that it should get darker in front of the car when switched to bright. I can't stand this, it fatigues my eyes and makes driving long distance at night exhausting. Most of my driving is rural county roads or interstate. The county roads are not smooth asphalt, but uneven oil and chip. I just want white even light covering all the area right in front of the vehicle all the time (which means I really need hid projectors lamps.)
