I am going to update the headlights and wiring for my Dodge, you know, power supply and relays plus I got some really cool ceramic sockets for Christmas.
So do you sages out there think pulling voltage from the alt. for the passenger side and from the battery for the drivers side to be overkill?
The relays actually don't cost that much and the voltage loss would be almost nill. The wiring up of this set up has been written about many times on this forum so it doesn't sound undoable.

 

Power both relays from the same source. No need to get really weird.

 

Ceramic sockets for the headlights?

 

yea, they weren't very expensive, soldered on pins and 12 gauge wire with 4 foot leads. Maybe 10 bucks a piece. If anybody wants I can dig up the name of the web site.

 

+1 on what HeyYou said.

 

if you do decide to install some relays you should maybe think about installing one that allows you to turn the low beams on while the high beams are on if you want. i have read it should make a huge difference.

 

Check this out its called the bright box and does as crazywolfe describes

why the heck would you want to spend $100 when you could probably make your own for about half the price? i picked up 13 relays and a whole bunch of fuses the the junkyard for $10. when i get some time i am planning on wiring up the headlights the way i would like them.

 

what do you think would be the amp draw with both lights on? I live in the city and dont get much chance to use the high beams. Brights on, here comes someone , Brights off.

 

i guess if all you do is city driving then you may not need it was just an idea. i am not sure what the draw is on the newer truck but on the older trucks it is about 65w per light that would be on so it would be about 22 amps with all the high and low beam on on my trucks.
