Installing strobe on factory light switch

    I'm not sure if other truck brands have this, but my chevy has a factory installed "axiliary roof mounted lamp switch". I want to use this switch to turn on my strobes. It's a two head system with a Whelen CS240 power supply. Instructions for the power supply call for a 10a fuse and a 15a switch. The lit. from GM says the factory switch has a 30a fuse under the hood and runs 12 gauge wire. Should I change out the 30a fuse for a 10a or 15a? I trust I wont have any issues with 12 gauge wire.

    I'm not worried about the switch being able to power the lights, but rather will it supply too much power on a 30amp fuse if it should only use a 15amp?

    Just go with the 15A to be on the safe side, it's not going to hurt anything.

    I agree with Blueline... Change the fuse to 15 amp it will keep things more in line if you have any problems.
