Adding bed lights

so i want to add a couple strips of LED lights in my bed for some light. i know LED's dont use a lot of power, i was going to run a line from my aux. fuse box to a switch to the lights. here's my question...do i need a relay for LED lights? i've run neon lights before simply tapped to a power constant in the car with no relay, i wasnt sure if i would need a relay for this or not since i'm coming from my aux. fuse block.

 

If you just want them to be turned on/off with a switch, then no you don't need a relay.

edit: I have a wiring diagram of how I did mine on my cardomain page

 

I'm doing a write up for my lights in the bed soon I'll keep you updated.
