Head Lights

Any one have them Custom Headlights from LMC? on there trucks

[Uncle Skip]

Yes, but not from LMC. Upgraded to Halogen's and using relays to switch the power directly to the lights. What is your question. I don't know if it makes a difference (I'm sure it will) yet because I'm in the process of rewiring my truck right now. I'll let you know.

do you mean the ones with the turn signals in the lens? several have them on here.

Im going to replace my headlight wiring and run them through a relay off the battery.

Just the rewire will make them much brighter.

I did the relay stuff but now my pass side lowbeam went out! was fine for about one night!

Check your wiring, especially at the headlamp socket. If you have the original sockets, ~ fifty years of use and newly increased voltage may have overheated the wiring, OR it may have just finished off a worn headlamp. These trucks were notorious for "flashing" headlamps due to overheating having tripped the breaker. Hopefully, you have included a correctly sized circuit breaker on the load circuit.

I did just what it said to do over there on FTE. Other then im running 12ga wire fore the headlight now! not there 14ga said to use. I went down to auto parts bought some more sealedbeams 10hrs on them now no problems yet! Other then all my lights kind of get bright then dim! Alt light flashes some! I have a good Bat good alt! New Voltage Reg. So why would the lights do that GROUND maybe? I've never had a prob with my Lights FLASHING + have I never seen that! Unless every one is talking about them getting a little dim and bright, and calling that flashing.

The flashing is the result of the circuit breaker tripping, then resetting, due to overload or age. If you are running relays, you won't likely have an overload at the breaker, as it is now just suppyling relay switching power. Definitely check your grounding, also check for heat at the headlamp sockets after extended use. The alternator light action indicates that the circuits are trying to use more than what is available at the time of dimming. Pay particular attention to engine-to-frame grounds. If you have new, good quality sockets, then they are not likely to be the source of the dimming. I'd do some voltage drop testing to see if a poor connection may be the problem. A poor or intermittent ground will often show these symptoms; the circuit will attempt to seek to ground through whatever is available.. You can jumper the ground terminal at each headlamp connector to see if this results in improvement.
The 12 gauge wire would have been my choice, also. You now have a more direct, shorter path which should increase voltage at the headlamps, so I'd rather have the heavier wire even though it may have slightly more resistance. I'm assuming your relay load power source is at the battery or solenoid; if correct, I would not expect dimming to be from that circuit, again assuming good terminals and connections.If you suspect the relay itself, do some voltage measurements at the relay load terminals. It sounds as if some other circuit(s) may be the source of the dimming. It may take some patience to check voltage on likely circuits once the dimming is evident, but that and the full voltage drop check will most likely identify the problem.

Check Evilbay for headlights. mine were cheaper than LMC and work well.. Also, do the relays, the lights will blink on and off without them. Cops are not amused...
