The LED porch lights I'm mounting have external switches. I was wisely advised to patch an internal switch into the ciruit so I could see what goes bump in the night in safety. I purchased 2 16A 125V AC rocker switches like the one shone here. Is is safe to use these switches on a 12V DC circuit that is fused for 20A ? I think I know the answer to this, but maybe my assumption is incorrect.
20 amps of LED lighting would probably be enough to guide the Space Shuttle down from orbit. Your current draw is likely in the range of .25-1 amps per light, so the rockers are more than fine.
