OK on that, yes lower wattage but they still should be BRIGHTer !
The thing I worry about is too much draw on the wire and the only thing that will happen is the wire will heat up; heat up enough and FIRE !

My worry is the same as Buggman’s not enough current is getting to the lights, too much wire can cause this. Long runs of wire in the cab and back out carrying full current is what I am talking about. Too much of a possibility of a shorted wire and fire.

I am not trying to be an @ss here, just trying to help out a possible situation, so if I am wrong then it won’t be the first time or the last.

Do you know what gauge wire he used ?

Not that he will change anything but rule of thumb is as stated earlier, "Two Lights per one relay and heavy gauge wire, both rated based on the total amperage draw of the lights.

 

I agree with you on this! check out my other comments on this thread, I told him he's playing with fire <-- pun intended

 

Good luck to him... They look good and good job.

 

I was just at Advance Auto Parts and they have the whole kit (wiring, relay, and switch) for only $11. They have the relay seperately for $5.

 

Watch out for the cheap kits.
Just because there is a relay doesn't mean all of the components are rated the amperage level you will need for your application.

Most light set-ups need 14-ga power minimum and some of the kits use a 16-ga wire.

Always check the current/amperage rating of the kit.
