i am wanting to when i put on my brake for my (red) under lights to turn on. I already have 4 off roading lights installed underneath my jeep so how would hook them up to my brakes??
 
I would suggest you try hooking them right at brake light switch to try and get the line before it gets up into column and goes through the turn signal switch! The turn signal and brake circuits get mixed in the switch, - so that the same bulbs work for both (depending on selection). If this burns out the switch, or blows the fuse, - you may have to put in a relay. This is because the lights could possibly draw too much current for the brake light circuit!
 
I also am against ricing of any vehicle. how ever if you must all you have to do is crawl under the rear of the jeep their should be a set of 3 wires that branch off and go to both of the taillights. get a test light figure out which one only works when the brakes are engaged and Connect the wire for your lights to that wire.
 
just find the positive wire on it when you mash the brakes,this way they,ll only come on when the brake is on,those actually look good on certain vehicles,it wont rice it up to add those to it,only make it look better,you could come all the way off the brake light switch to do this but its better to do it in the wire its self,good luck with it.
