O.K. I couldn't find the military version so try these: http://www.buytruckstuff.com/ledlights.htm#
Those are the 4" truck lights. There are smaller marker lights that would fit inside the stock housing. I have found that they work on as little 9v, and was told they handle up to 36/48 volts. I got one as a test unit from Freightliner for eight bucks. Take it for what its worth. Sorry again.
