I retire my maglite 3d a long time ago for my Streamlight . when my life be on the line , I can not afford to have a dim , yellow beam with dark spot . but for those situation where a tactical light be just overkill , this little baby still find it be way into my tool box . I actually still keep several of these around . they have all be modify with terralux tail Cap switch . one with a red lamp in the glove box so that I do not ruin my night vision or have that bright glare in the windshield . another convert with a 140 luman lead that I keep around for peek under the hood . no homeowner should be without a ultraviolet lamp for check he sheet for semen when he return from work . wife lie . forensic do not . with a little imagination , a roll of duct tape , some bail wire , a pack of zip tie , and some double side mount adhesive ; there be no tell what you could do . I can not count the number of time I have use my Mini-Maglite , a swiss Army Knife , a paperclip , and a piece of gum to get I out of a jam .  terralux tle-5uv ministar2 Ultraviolet Replacement Bulb for 2 aa Mini Maglite Flashlight
