I have carried a flashlight every day for 15 years. Hint: That's a code book in the photo.
TacoDude has got it going on. My setup is similar:
What you want is a streamlight SL-20XP. It is LED/Halogen, charges in the bracket, 1/3 the weight of a maglight, 2x the output. Almost indestructible: Have dropped them two stories no problem. LIFETIME warranty: cop shop in our town does it while you wait. One of my older ones probably has no original parts left. I own 4.
I have a couple of the stingers, but I really, really prefer the SL-20 series.
Sorry boys, but Maglights are not good flashlights. They are bad hammers.
Streamlight fits nicely on the rear side of the B pillar near the floor.
[I have a LOT of portable lighting. Check out the half million CP.]
