I've read most of this thread and it's been very helpful. I'm building a system with a 7.5 aH SLA battery, Optronics driving lights and a Vellerman strobe. I'm going to use a 20W spot and a 20W flood Philips Energy Advantage bulb. I am going to use two switches and a diode to allow independent use of the two headlights, with the taillights on with either headlight. My one concern is connecting all the wires. Right now I intend to connect everything in a black plastic box using wire nuts. It seems to me there might be a better way, but I can't figure out what it is.
