relay or no... please let me know

So i was just wondering if you have to have a relay to run off road lights? I wouldnt think you would have to and what would happen if i didnt? If so how do i hook the relay up? thanks.

Fire bad, relay good. Use relay.

A relay will keep all the higher voltage in the engine bay and out of the cab. Can you run lights without? Yes. Are you better off with? Definitely. Less than a buck for security. Money well spent.

You should always use a relay.

I'm running 900 watts of lighting on the grille of my M1009 and a relay isn't an option; I had to use a 12v solenoid to switch the power from the 24v bus bar.

I think the word you are looking for is amp not volts. Its all 12v in a jeep.

What kind of lights are they? LED setups can be done without relays. Most other types should have relays.

I generally use a 10 amp total draw as my threshold for relay or not. Most good quality switches can handle at least 15 amps easy.

This is for any assy, lights, amps, etc. more than 10, use relay.

Like said above, LED setups can draw as little as 3-4 amps.
