lights dim with off road lights on

My dash lights dim when I turn my off road lights on behind my grill. Is this normal?

I don't know how that could be he has two 130wats behind his grille i think. I have that hooked up to stock battery among other things and have no problems.

it depends on the CCA on the battery too and what other electrical components he has hooked up that can cause a strain on the battery and alternator

they are two 55 watt **** cepek lights. I ran them to the breaker and battery then to the switch which branches to the running light wire. Does that sound right?

okay good circuit breakers should never be used for cars haha, just ask for a wiring diagram and double check to make sure its wired up properly, but you are still creating a draw on the battery and alternator whenever you turn the lights on and thats more than likely going to be your cause

So it is not because I went to the running lights behind the switch?

My headlights and fogs went dim when i first wired mine up due to a bad ground.Turns out i didnt tighten one of the ground all the way.

Sounds about right. My lights run to a relay mounted under my dash. Then the relay goes off to the switch and battery. I would check your ground and make sure it is good.
