I've been going through a lot of the driving light threads and I can't find the answer I'm looking for. I'm purchasing a set of PIAA lights and the mounting kit but I want to wire them to come on when the fog lights are switched on. Is this possible? Thanks in advance for any advice.

 

In the USA you are limited to how many lights you can have on, I believe that would be too many. My driving lights had a relay that shut the fogs off when I turned the driving lights on.

 

I'm not really concerned about being pulled over for two many lights being on i would like to have them come on together plus I want to control them with the toggle switch for the fogs. Thanks for that info though.

 

Your PIAA light kit should come with a relay and instructions that tell you to wire the relay up to the high beams. If you really want the driving lights to come on anytime the fogs are on, just wire the relay to the fogs instead. Be aware you'll have to manually turn off the fogs (and the driving lights) when you meet opposing traffic.
