12v Headlight wiring

Duke83 · Sep 30, 2012

Does anyone have a diagram for wiring headlights for a 12v system. When i bought my 1948 8n the headlights were not wired. Just want to make sure I do it right. Thanks

JMOR has them on his wiring diagrams if you search for those.
Pretty easy, just hook from the battery post of your resistor to the light
switch, then to the lights.
You don't want to hook to the side of the resistor shut off by the key.
It may sound good but the switch can't handle the current flow.

Thanks, that sounds easy enough.

Are the bulbs new 12 volt or original 6 volt?
original 6 volt would have to be wired in series (12 volt in to one light terminal, out the other light terminal, to next ligght terminal and last trminal to ground. It takes the resistance of 2 6 volt bulbs to equal 1 12 volt bulb.
New 12 volt bulbs are hooked 12 volt to ground in each light holder.

Most recommend running a ground wire to the headlight to the frame due to paint, rust and corrosion issues to the sheet metal. HTH

You might want to add an in-line fuse as well.

no diagram needed. lamps ar ethe most basic circuit you can get.

brab power same palce ignition does.. use a fused switch of correct amperage.. run wire to lmaps, ground lamps. sheetmetal may not be a good ground...
