Headlight relay upgrade question

Guys, I would like to upgrade my stock wiring set-up for Headlight Relays, but not sure what kit to choose. I have sealed beams right now, ('68 C-10), and would like to install relays before I decide to upgrade lights, (if needed afterwards - I hear this change alone can improve brightness performance). Would really appreciate advice on what you may have used, and that you liked. Thanks in advance, Ned

Re: Headlight relay upgrade question

I got the same type setup from LMC. One of the relays went in a matter of days. I bought replacement relays from Summit and its been OK for a couple of years. I also got the lens gear for lamps to replace seal beams - major improvement.

Because of a LS conversion I reversed the intended direction and moved the relays to the driver's side. I took the harness cover off and ran the wires through the original side to side wire 'loom'.

Re: Headlight relay upgrade question

Thanks for the advice. I did order the LMC harness with 2 extra relays to have on hand.

I made mine for less than $10.00.
I rewire golf carts all the time so the wiring wasn't a problem.

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

Re: Headlight relay upgrade question

I'm doing mine this weekend. I have about $15 in mine since I needed to buy some wire and replaced the sockets to the headlights. Any tips Andy?

It's a pretty easy upgrade really.

Take a test light and pull the head light connector off the drivers side light.
With the test light on one of the contacts figure which wires are which...High/low.
The drivers side connector works both lights.

Then cut them about 12" away form the light.
Take the end from the harness and this will be your trigger wire for the relay # 86 in the picture to the H beam one you are doing. Then the end to the head light goes to #87.
You can run a #10 are #8 wire from the battery for the hot wire to the relays # 30 on both with inline fuse.
Then ground each relay #85 to a good ground close to the relay.
Repeat this for both relays.

Re: Headlight relay upgrade question

Put a set of H4 LED's in it instead of Halogen upgrades.

They are WAY brighter and do not require a Relay upgrade.

Re: Headlight relay upgrade question

Just finished my relay upgrade. Less than $15 since I already had the wire. New relays and headlight sockets. Now have 14 volts at the lights. Havenít had a chance to drive after dark yet but they appear much brighter.

Now with the new brightness make sure you aim them good to get full benefit of them.
