I have a 2008 dodge ram 1500 big horn and I was trying to figure out how to make my fog lights stay on with my high beams on. Dose any one have any ideas?

 

Might not be what you want to do but wire in a switch

While I agree that the OP should search before posting, the courteous thing would be to answer their question as well.

I refuse to answer b/c the OP has not searched for one of the most commonly asked questions...

 

It can be done by adding an additional relay under the hood, that is properly rated for the current load, that is tapped into the fogs and fired by the high beam "on" voltage from the high beams. By doing it this way, the normal functionality is maintained by the switch inside

 

That will not work on 2006+ trucks.

 

Good call, I did not catch the year of his truck.

 

Buy HIDs and you wont need to do it. Buy HID projectors (not cheap ebay projectors) and they will be even better
