M1097R1 Brake Lights Inop

The bulbs work, turn signals work but the brake lights don’t. What could it be?

Brake light switch would be the most likely and easy to test possibility

Where is that switch located?.. Also I test to see if the light bulb socket is getting power and it is

Turn signals work, so the sockets get power.
The switch is under the dash. Follow the brake pedal up to the thin wire linkage to the switch. Loosen mounting bolts to slide the switch for adjustment.

Mine was inop when I got my HMMWV as well. In addition to adjusting the switch, I used a couple of zip ties to stiffen the unit up some. That was many months ago, it’s still going strong.
