Unless the wiring is 12awg already, then yes you do need to upgrade the wiring. The amount of current being drawn through the wire will be insufficient and heat up the wiring causing the insulation to melt. The max amount of current a 12awg wire can handle is 25amp. 2-150w bulbs is right about 24amps. I would say 130w bulbs max for safety on a 12awg wire.

My guess is the wiring is 14awg and has a max rating of 20amps. The 100w bulbs draw a little over 15amps for the pair. 130 will draw 20amps.

Your truck with 6-100w bulbs is drawing about 50amps all together when they are on. Just to give you insight, your high beams only draw 10amps when left on.
6-150w bulbs will draw almost 75amps with just the flick of a switch! Instant drainage....lol

 

Does anyone know where to find roll bars/light bars/bed bars (whatever they call them now) for a 07 Ram QC? Thanks

 

JoeHemi Ive seena bracket that mounts to your third break light to mount two lights on it. I'll do some searching and let you know where I found them forsure. Maby Autoanything.

 

I just piced up the PIAA 540 Xtreme white lights to day. They are 55w whitch equal 110w out put. I need to take some pics and post them for y'all. I'll probaly install them this weekend.

 

you could always get one of those rear window gurads or headache rack that wawy you can keep the box and mount lights on top of the rack like 6hemi did

 

 

KC Hilites on mine. Nice throw on dark country roads.

 

looks good, thanks for puttin up the pics. I've been getting some ideas of what I want to do.

 

Joehemi I found that light bar for the third breaklight,its on stylin trucks.com
