JOY! I just ran across a computer UPS unit that was going to de disposed of (not because it was dead, but no longer needed) and lo and behold, what battery does it have in it, but a 12V 5AH SLA!!!

So now that I have the major piece of my possible lighting scenario sourced, I'm thinking of getting the Optronics MR16 housings, and some 20W or 35W narrow flood bulbs (or a spot and a narrow flood, for better coverage). My commute will only be about 45 minutes at the most, so I'm pretty stoked about this!

Any advice besides using quality wire and switches, and a good fuse/breaker? Any type of bulb I need besides a covered one?
