I enjoy flashlights immensely and have squan...uh, spent, quite a bit of my non-expendable income on some pretty high-tech "flashy" (sorry) ones, but IMHO the best trucklight ever is the 3 D cell camo Maglight that I got many years ago and which still sits under my truck seat readily at hand. As soon as I got it, I took some water hose and slit it up the side, and inserted 4 C cells instead of the 3 D cells, and removed the bulb that came in it and put in a 4 cell krypton bulb. When they became available, I got rid of the krypton bulb and now it has a 4 cell LED bulb in it. Nice and bright and powerful and rugged with a tight penetrating beam, and an acceptable good mood alterer also if need be.
