Lighting switch power wiring?

Got an electrical question for you guys. Adding uptop roof rack with 40” bd s8 and 4 bd rock lights. S8 has amber led backlights. I think 4 small leds so not much power and the 4 rock lights draw 4 watts each. I’ve daisy chained my switches and plan to use add a fuse to power the rock lights and back light on light bar. I have relay for main light bar power to blue sea fuse panel but will add a fuse handle powering the rock lights and amber backlight on s8 without relay? I planned to use add a fuse to ignition powered fuse in dash panel. Does this plan make sense? Should I wire the switch power back to blue seas panel instead for some reason? I also prewired 2 extra switch backs for accessories down the road. Is it fine to have these empty switchbacks until I add something later. Thanks for the help as I am a noob with electrical.

If those are the carling switch they are rated for 20 amps I believe. Add up all your lights wattages, divide by 11 volts, and if it’s greater than the switch rating, your answer is no.

 

Thanks. Asked around and think I’m in good shape. Lighting wattage is less than 20 amps
