Dim headlights at idle....simple fix?

[Justins72]

would you need 4 relays since for a challenger since it has 4 lights or just 2 (one for low and one for high)?

no still just two relays. 2-headlight cars have three wire bulbs, high, low, ground. 4-headlight cars have low-ground & high-ground.

 to state it clearer 1 relay for low beams circuit
1 relay for high beams circuit no matter if you have 2 or 4 lights on the circuit the draw from 4 lights is still far less than the 30 amp rating of the  relay

While not the cheap route, I just bought and installed the Painless Wiring headlight relay package and drove it just now at night.  WHAT a difference.  Thanks to all for the info! 

One issue/concern checked off the list!

I can see, I can see!!!

Very glad to hear it worked out for you! did you do any voltage checks before and after?

Naw, I forgot to....

I work afternoons and got off early (11PM) and got home...wife and kids asleep so I decided a good time to start drinking and working on the 'Cuda!

Next thing I know its 3AM and I'm sitting in my driveway in the 'Cuda idling with BRIGHT headlights!

Nothing like 5 hrs of sleep!
