i use the stream light from bass pro. like 20 bucks, has 3 settings from 1 green led, 3 green led and a white xenon. Ive had my two for years and ill ive had to do was replace batteries.
Man you cant go wrong at all with streamlight. I have a headlight as well and i also carry the pen one in my pocket. That pen one is like 30 bucks but dammm its well worth it. Bright! I also bought that streamlight spotlight wich im really pleased with. It has a 12v conection you can use For the truck or if not you take that off and slap 4 C batteries in it and take it with you not heavy at all. Still on the same 4 bateries from wheni bought it months back
