Ok im getting a new light bar with 4 of these lights, i need to know if this switch will activate all 4 lights or if i need to buy something else. here are the links:

Lights:

Switch:
All help is greatly appreciated, im not experienced in these things

 

Should work. At most, 4 of those will pull 18 amps, switch is rated for 20. I recommend relays though.

 

Ok what are relays?

 

I put this in another post a few mins ago and it was actually still on my clipboard hahaha

Ok so lets say i have the 4 lights on my light bar, theyre connected to the switch, wheredo i put the relay?

 

I would recommend having it installed professionally. However, relay would keep all that current out of your cab and allow you to run higher gauge wire inside and a lower rated switch. Without relays you need 12 gauge wire in cab to the switch and then to the lights, which would be in series. With a relay you can run 12 gauge to the relay then to the lights. Then run a 20 gauge or something similar from the relay to the switch.


** current creates a lot of heat..you really don't want all that current running through a switch. Even though, 18 amps isn't much compared to, say slimlites at 130w a piece. You could get away with not using a relay for those, I just don't recommend it.

 

This is gonna come off like me sounding like a jerk (it's not intended), but if you really haven't done any electrical work before or have no general knowledge of such, bring it to a shop or have a buddy who has some knowledge help.
Would hate to see a rig lost to an electrical fire due to faulty wiring.

 

ok, i understand, thank you

 

The lights aren't directly connected to the switch. See the below picture. The relay separates the light circuit from the switch circuit.

This is great advice to someone who hasn't done circuit wiring before. The PO on my jeep hacked together some fog lights and I about used every swear word possible while fixing what he had done.

 

Like I said, I'm not trying to be a jerk. I can't express emotions over the internet. But, I'd hate for you to put your life, anyone who rides in the jeep, and the jeep's life (lol) in danger. I mess with a lot of things (minus drugs and all that weird stuff). Electrical and when I cook at work, I don't mess with. I take all that stuff seriously as should everyone. Thanks for understanding.

 

The harness that comes with the lights may already have relays built in.

 

This is also a good point.

I always forget that because I typically do my own wiring.

 

Best example.
