Welcome to the club!
Miss my m915a1, she was awesome and I really liked the look. I have a m915a4 now.

Good luck with her! The headlight switch is usually an issue the stock one was barely able to handle the load. Highly recommend putting in a heavy duty one or adding relays. Mine would leave me on the road in the dark when I first got her.

Ok thanks for the heads up will look in to the switch

I made a switch for the headlights themselves. Tail lights etc on their own switch as well with their own fuses to correct the switch overload

 

[panzerwillie]

That is my plan as well thx

Pretty sure that was just you, not the truck. Nothing could be wrong with a good running 915A1.

Thank you , who makes a heavy duty one maybe easier that doing relays but I am able to do either, also what was the fan switch temp to activate the fan clutch the local store has a 185* and a 190* NC switches...

If you install LED headlights, the stock switch will be adequate, and you will see much better at night.

 

[panzerwillie]

That's a idea as I need to replace the bulbs, does the LED from the Hummers work are they like the markers where they have 12-36volts range or is there a brand you recommend.
Thx willie

Any 7inch 12v light will work. Some amazon ones are cheap but work well. The replacement switch will still overheat even with LEDs on everything. I run thr trucklites with heaters since i can get them from any truck parts place

I am fully aware that any 7" will work and the switch needs help , just wanted to know about the HMV leds , will incorporate relays on the system to take the load of the weak switch thx for the imfo.

There is no specific HMMWV LED Headlight. There are several makers and types used by the military so you will have to be specific on which one of the 6 or 7 different types there are you want to use. Most are omnivolt but there are some that are not

Ok thx for the education
