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'. |

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. :chevy: |
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. |

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. Haven’t had a chance to drive after dark yet but they appear much brighter.

Re: Headlight relay upgrade question
the relay upgrade isn't just about brighter lights . it takes a significant load off the mile and a half undersize wiring and headlight switch when going with modern lighting . if you take a voltage reading with a good meter you will see sometimes 10 volts or less depending on condition and age . the original lights would light no problem be it a little dull but those modern lights including those led like the full 12-14.5 if you want that life expectancy and brightness your looking for . if your buying a harness from lmc or any other you might want to upgrade to some good bosh 30 or 40 amp relays they will last much longer than the ones that they buy for super cheap and put in to keep cost down . even if your not doing a light upgrade its a worthwhile mod to take the stress off that 50 year old wire all the connectors and headlight switch . and dont forget to make sure those grounds are in great shape
