Headlight relay good idea?
Been sorting out a problem in my 12V negative ground electrical system. Does anybody know how many amps headlights on high beam and tail lights draw? Ron Francis says more than 15 amps I need a relay, any thoughts on that?

Re: Headlight relay good idea?
What headlights are you running? If those are the original lights I would suggest the "Brite" bulbs from Ron Francis (I have them in my '32 and they are great) and he should be able to give you that data. While you are at it get some bright tail light bulbs and ask him how many amps they run.

The great advantage of the relay whatever the current draw is the better electrical connection in the switching process. Not so much with 12v but still may be worth considering if you are using the original Ford light switch.

This is a relay diagram using Starter solenoids (12 volt solenoids). You can do the same thing using normal 12v relays.

Using modern relays, a 30 amps relay for a auto supply store should be fine.

Am using regular 12V bulbs, not halogen.

Re: Headlight relay good idea?
Relays are always a good idea Bob, I have halogen globes ohh I do feel sorry sometimes for those in front.

Re: Headlight relay good idea?
My light switch is dash mounted from Speedway, pull all the way out and you have hi-beams.
Looks like there may be a little more involved for a headlight relay than the fan & fuel pump relays I installed. Might leave well enough alone, everything seems to work as it is. Did see a relay with two #87 posts, does that mean I would only need one relay rather than two? Last edited by 36tudordeluxe; 04-19-2016 at 10:04 PM. |
