Just finished installing a relay in the high and low beam lights, on a 69 lwb.
If you have not done this install, you should. This is the second truck I've done. Cost is about $25.00-$40.00 depending how much wire, relays and split loom you want to replace. This mod will payoff rightaway. ![]() ![]() ![]() Bright light, Matthew Last edited by matt67350; 09-17-2005 at 04:18 AM. |

The wires are too small, the length is to great, the result is less than 11 volts at your headlights. And all that missing current has to go somewhere. Where it goes is it turns into heat which wears out your $8.00, pain in the a$$ to change headlight switch! What you do is turn your headlight switch into a relay controller. Use 8 or 10 gauge wire from the battery through the relay to the headlights. The result is 12+ volts at the headlights. The first night you run with these you'll wonder why you waited so long to make the swap. You'll also wonder why people are buying those $40 each headlight "upgrades".

I was planning on buying one the headlight upgrade kits and didn't realize I would be frying the headlight switch over the long term!. I will look into that kit from Summitt.

no headleads
See here everyone talking about the headlights. I am handy, but when it comes to wiring, i have to left hands. I think this may be my problem. I put a new high/low switch in as well as a new h/lamp switch. I have dash lights, tail lights, directionals and brake lights but no h/lamps either high/low beam. Any info on what I am facing here would be great. Thanks to all for any input.

I have done it, can't believe anyone with a daily driver that sees night driving wouldn't do it. It makes night time driving 10 times better. One of the cheapest bangs for your buck.

Man, with all this talk, its looking like my headlight system is getting a second and third relay, lol (I've got it rigged up so the headlights are on when my heater fan is on, that turns them off when you are cranking, but on the rest of the time)
My lights were good before, I'm excited to see how they'll be after I do this little upgrade! I never even thought about doing so before ![]() I think these will be relays number 20 and 21 or so on my truck, lol

Chevy is the first, and GMC is the second.

The GMC schematic has only one 20a fuse feeding 4 headlights. For better circuit protection use two on the feed wires like the Chevy.

I've done it on several trucks.
(the summit one) Lengths are perfect, in fact, too long. I usually cut 'em down. A bosch relay, in 20 amps is perfect for DIY. |

Do you have sealed headlights? If so, no bulb replacement. I've also used the Sylvania upgrade (cool whites? They suck) and the Hella one. Hella makes a better light, with replaceable bulbes that uses a H3 headlight bulb with an open housing. ![]() http://store.summitracing.com/defaul...=egnsearch.asp AND if you're really mean, you can put the "offroad only" bulbs in there...
