I picked up a pair of cheap chinese made driving lights for 10 bucks on sale at Harbor Freight. Want to mount one under the truck and use it as a backing-up light.
It's a 55 watt bulb...so it draws roughly 4 amps.
I'd like to just hook it up to the existing lead going to one of the truck's reverse lights. Think the truck wiring would handle another 4 amp load back there, or should I run 12V to the rear and through a relay using the truck wiring to just pull in the relay?
I know the circuit is fuse protected but I still don't wanna take chances.
