Been searching on here for some answers to a couple of questions.

I want to install docking lights on my tower. Plan on using a "driving light" style 12v automotive light, either halogen or led. I like the automotive kits because they are relatively inexpensive, and their use will be infrequent so they should last awhile.

If I install these, I plan on using one of the two unused accessory switches on the dash. Do I need to install a relay in the circuit? and if so, why? Does the relay keep the current from the light from running through the switch on the dash itself? Most of these kits come with their own switch, and no relay supplied, just an in line fuse. Do I need to install the in line fuse, since the switch is already CB protected?

Thanks.
