okay i was thinking about buying 4 more 100w KC day lighters and making a light bar for the roof of my truck. i am already running 2 kc's down on my bumper. with this many lights drawing power how could i wire it up so that it will get the power it needs. also im going to mount the light switch up on inside by dome light(thought that would be cool). any suggestions?

 

I ran them the same way as the two just ran a bigger guage wire and bigger fuse.

 

i just put 4 KC's up top on a light bar also. i need to redo the wiring but they run pretty good for what i got which is just what they gave me in the kit.

 

the Roof harness is a hefty price but its a great thing from KC... check the KC thread i made for everything you need... and you will enjoy the lights i know i do... except stupid little 100W.... PFFFF






i use the big boy lights...

 

lol..


use relays...

you can then trigger the lights on with only a simple ground signal..


JOSH

 

thats pretty impressive lol

 

Looks like a plane coming in for a landing.

 

Some people actually use airplane landing lights, anybody ever try them?

 

KC lights come with one it comes with a full wiring harness nothing extra you need to buy ...

 

yeah i think im gunna have my friend make me a light bar for the top. but what size wire should i use for the 4? and should I piggy back them together and just run one wire to the ground and such?

 

12 gauge wire would be overboard (but not bad), and 14 would be fine. i would personally run each 2 lights on one relay, and then run 1 switch to each pair of lights.
you can run each 2 lights together to a single ground. i wouldn't run the 4 together to one ground b/c you would need to up the wiring size, and there really is no point to have to purchase and use a lower gauge wiring just to run them together when the kit will provide what you need.
here is a decent wiring diagram that is simple enough to follow. i personally prefer to run the switch's power wire straight to the battery of course using a fuse.
