>>1310182>arbitrary reasons:-It's a round beam, on a moving vehicle. Not enough light where you need it, too much wasted or dazzling oncomers. The mark of the asshole.
-A zoom lens is pointless, you will always want the same beam shape, and zooms always have horrible artifacts.
-Battery powered. You need to unclip it and bring it back and forth into the house for recharging, never charged when you need it, and if it's really 7W it won't last long. Doesn't work in the cold either.
-Fucking blinking. GTFO.
I must say though, that's a heck of a lot of flashlight for five bucks!
