Headlight relay kit
Just wondering if anyone here has installed the headlight relay kit that is offered from LMC Truck. Is it worth the trouble? Or even necessary?
Thanks,
John

It lets the bulbs get the full 12-13v vs 10. Stock harness has resistance and uses some volts up.

, and burn up 2 switches, then you will want the harness. I have it on 2 of my 3 trucks at the moment. Probably put it on the other later, but the 88 F150 has a different style switch, so it might be better than the 92-up switches.

It is a set relays that hook directly to the battery +post at the starter relay, and then feed directly to the headlight bulbs with fusible links, and larger wire. The orginal switch in the dash, just turns the relays off, or on only. Relays use very little power, so no more bad switches, or burnt wiring harness pigtails.

That would be only under heavy electrical loads like e-fans, stereo's or etc. for the amp draw. The voltage is suppose to be the same thru out the system, but wiring size, connections, and length cause it to lower. So, there will be a difference in volts from the battery to reading the light bulb voltage thru the stock wiring harness.

curious - is this the kit to turn on the lows when the brights are on (like chevys for example)? if so, Id avoid it cuz having both filaments on in your 9000 series bulb will melt it - literally.
(I used the brights+lows 'kit' on my k2500 by making it myself - 20A breaker, some wires, shrink tubing and a relay - about $8 my cost.)

I was going to do the same mod but use the old harness... now I'm thinking using thicker gauge wire is probably a good idea... from what I've seen you could build your own " kit " allot cheaper than buying the one from lmc
