My bed lighting is from roundeyes.com. I tapped into the hitch plug running lights. My switch is from my rigid industries wiring harness. I'm happy with the set up. AUX usage seemed the wrong way for me to go. I like having the switch back at the tailgate.
lol what a website name. They implying they're not made in China? lol
I like the idea except that the vehicles electrics are built for a certin wattage... You should make sure you are not over working the system... So, if you have a power source and it has 20 watts available and you are using 15 and you add 7 more you are drawing 22 watts now and the lights will not be as bright and you can burn fuses or the wiring itself...
If you're on the same circuit that the trailer lights would be hooked up on, you're fine. LEDs under the bedrails are going to be drawing such little current. Especially if they're on the circuit that if you plug a trailer into, you're running all those lights off the same one.
