On second thought, since it's cheap and rack mountable, AA, and built in reflector maybe I'll get that Serfas just for the heck of it, and maybe add on the Zebralight I mentioned earlier for added punch, and a 100+ lumen strobe for daylight.
And then if I get some free time, maybe I'll just fabricate my own taillight, since I know the technology is out there, just that manufacturers aren't attempting to make what I am looking for. Maybe a winter project for next year.
I use the Serfas as a rack light in addition to Cygolite Hotshot 80. I made it non-removable by drilling its back panel & mounting it permanently to a rack with a bolt and nut. But if you need it to be removed, you can get an optional rack mount for $6 on Ebay. So in case you decide to get Serfas, get one with an USB port. It is only couple of bucks more expensive but that way you won't have to remove the batteries every time in order to charge them.
