dual headlight systems work like this:

Low beams have 3 pole sockets

hi beam bulbs have 2 pole sockets:

when the low beams are on the low beam lights come on, when you turn on the hi beams the power goes to the hi beam bulb as well as the hi beam bulb in the low beam bulb.

Do it with relays, it will make the light a lot brighter since the bulbs will be drawing power directly from the battery instead of through the headlight switch. Kieth


I just rewired my 66 gmc and it has 4 bulbs went to halogen bulbs (only $7.00 each) sure puts out a lot more light.
