FMTV, LMTV, M1078 Civilian Truck-lite LED Headlight Install

[Keith Knight]

Using the civilian Truck-lite LED Headlight. It also allows for any other civilian headlight to work.

Modified an H-4 harness by soldering some military connectors onto it.
First heat the connector and fill with solder.
Then while the solder is still fluid insert stripped wire into connector until its solidified.
Don't forget to put the rubber boots on before you solder it.

If you can't read the label... 17 top left is High Beam, 18 is top right low beam and 91 is the bottom Ground.
Lights on High Beam and no Flickering without using the anti flicker modules.

Where and what is the anti flicker modules, where do you get them and the price.

 

[Suprman]

I have used these in several trucks with good results, they have a better light pattern than the first gen led bulbs. They are 12-24 multivolt and I havent had any flicker issues. Some euro cars run a small voltage thru all the lights on startup to check for bad bulbs, not enough to light and incandescent bulb but its enough to flicker leds. Never seen this on military trucks though.

 

[Keith Knight]

Truck-lite makes them for the military. If you look at truck-lite web site and go to the military lights section you'll find them. I like them because of the black reflectors.

I've had them on my HET for over a year and never had a flicker issue.

Correct me if I'm wrong, but I think the flicker issues are problems that appear on pre-factory LED Chrysler vehicles. The power supplied to the headlights was pulsed at a rate faster than the incandescent lights would be affected by. LED lights react so much faster, so they would turn on and off instead of just staying on with pulsed power. I don't think you see flickering problems with LED headlights on older vehicles for the most part.

 

[Keith Knight]

I just wanted to be clear, I installed them and have NO flicker problems!!!

Where would a guy be able to purchase military connectors to do such a conversion?

 

[RAJ LMTV]

Did you get a response? Looking for these connectors also.

 

[Suprman]

I usually order them from Eriks surplus and crimp them on. I have short 4 wire extensions that have male one end and female on the other you can cut and crimp them to the headlights wire.

 

[parkinson6wa]

I have seen them at Erik's surplus and also on ebay.

 

[parkinson6wa]

My light terminals are labeled 16, 17, 18. How do those correlate to non military lights (+, -, ground)?

 

[MWMULES]

17 top left is High Beam, 18 is top right low beam and 91 is the bottom Ground

Thanks MWMULES. I felt pretty silly when I read the answer to my question in the thread above.

Every other light on my HET is LED already. Only the headlights need be swapped with LED bulbs, bought them, and can't get them to work. Looking for thoughts on why i'm having an issue with LED headlights working on my HET. The bulb headlights work fine, high and low beam. When i install an LED headlight, neither the high or low beams work. So i put the LED headlights into my HUMVEEs and they work perfectly fine there for both high and low beam. Wondering why those LED headlights work on any truck EXCEPT my HET? I can only get bulb headlights to work on my HET.
Second issue with the LED headlights is, even if they did work on my HET, the protective bars won't squeeze in to close all the way since the LED headlight bulb sicks out too far. What LED headlight bulb part number does the military use in their HETs? I'll try to find that part number to buy a set of those LED headlights instead. thanks!

I made complete new mounts with new bars for mine to clear.

that solves the bar issue. thanks. Did you have any issues with getting your LEDs to work? My LEDs are trucklite also, but won't work on the HET, they only work on my humvee. Is there some sort of adjustment i need to make on the HET to have the LED headlights to work? Is that why the Army had all LEDs EXCEPT the headlights?

That version of the Truck-lite headlights is voltage specific, either 12v or 24v. They are not multi-volt like the newer ones. The voltage for the headlight is on the back painted in yellow. What do the HETs run for voltage to the lights?

 

[Shark Bait]

If I remember correctly the HET headlights are 12 volt.
