Multiple rock lights on one switch?

Let me first say that I'm pretty much an idiot when it comes to anything to do with wiring....

I've found some small 55 watt lights I want to use as rock lights. I would like to run three pairs and switch them all with the same switch. I plan on wiring them in parallel and will use a relay. What size relay and fuse should I use? Is 12 ga wire big enough? Thanks for the help.

Send a message via Yahoo to benmar2000

What I would do is use 4 relays.. 1 relay to kick off 3 relays controlling the rock lights..

To figure your amps. Take the watts ( 55 ) and devide by the the volts ( 12 ) = 4.58 Amps. If I were you, I wold put two lights per relay. That would be just under 10 amps. Use #16 wire to each lamp. And use one switch to pull in all three relays. Use a 3 amp fuse to protect your switch circuit.

Thanks guys. I think I am going to use 3 relays and one switch - just to be on the safe side.
