I know this modification is not for everyone, especially anyone that wants to keep their HMMWV stock or stealthy. But if you would like to have dome lights that do not need door switches, or are not just controlled by a simple switch to turn them on and off manually, this setup might be for you.
I just finished installing this. When you open a door, the motion sensor detects your presence , and will turn on the dome lights that you install for any set time you would like. Sometimes if you walk by the vechile, they will also turn on without opening the doors. Perhaps careful adjustment of the sensor can change its sensativity.
Once you start the ignition, the dome lights will go out. When you shutdown the engine, the dome lights will come on, again for the set period of time you like.
I also install two rocker switches. One that I can force the lights on at any time. And other that disables the lights entirely when stealth is desired.
So far, it has not seemed to drain the battery, but I have not let it sit for months, just days in my case. Make sure you set the timer to turn off the display lights automatically after 5 minutes which does not seem to be the default.
Here are the parts needed:
Here is a schematic of how I hooked it up. This includes two optional switches, one that can turn the dome lights on demand, the other disables them.
