2015 2500HD Lightbar Lights


Recommended Posts

I've just mounted the N-Fab Lightbar and would love to see other 2015 2500HD's with their lights on a lightbar. The N Fab site has a 2015 2500HD with 4 - 9" round lights and that don't look bad. I'd really like to see what rectangular lights look like on the front, something like the KC 69 Series. I'm thinking with the square box front end, rectangular might look better, thoughts and pic?

 

Here's my lightbar with no lights currently mounted and the pic with round lights (not my truck).

 

Thanks,

Chuck

@Colossus I agree and I can't get use to the LED lenses. I found most do not put out the lumens a halogen can. So I went with the KC Rally 800 series, they're bigger than the sample photo above has. I haven't wired them yet, but I had to see what they'd look like so I mounted them for a few pics. I can't wait to see them lit up, I like the look but I'm going to have to get use to them sticking out a bit. I figure unless I went with something behind the grill, I'd have to get use to any light on that bar sticking out.

 

Here's a preview

I've seen some great light kits installed in a number of these forums. I'd be interested to see the creativity inside the trucks too. How are these being wired? Are you adding switches inside and if so, where?

I made a relay harness using a universal Bosch relay and mounted a lighted toggle switch by the headlight knob.

Thanks for the comments! I've been taking a lot of pictures, I know a lot of people want to see the wiring. Before I share what I've done I really couldn't have done this without the help of a previous post by colton_m and AZelkhunter and others located at this link:

 

http://www.gm-trucks.com/forums/topic/161931-need-multifunction-switch-instrument-panel-diagram/ You have to dig deep through the thread, but it's all well worth the read.

 

I used factory switches, I bought two switches to make one switch bank and changed out my current one. So I spent a little extra money but my goal was not to drill any holes or tap into any factory wiring.

The available switches from the dealer are all listed in the link I posted. I bought them from here,

I think about $50 a switch. I have a lot of detailed take apart pictures of these switches if anyone needs them, I had to break two unneeded switches just to figure out how to get them out without breaking the needed ones.

 

Picture limit forces me to continue my wiring pics in a different post.

So here's the utility box I bought from Fry's Electronics for the relays and then mounted the box in a spot near the battery.

The red and yellow wires are the only two wires I'm currently running into the cab. These two wires go to my aux 1 and my aux 2 switch. For me I crimped ends on them and put them into the factory connector Pin #16 and Pin # 9 at the back of the aux switches. I've cleaned it all up with wire loom. I'll post pics of the wiring going into the cab next.

I just couldn't bring myself to messing with the boot that goes through the firewall and comes out behind the j box inside the cab. So, I chose to go through the fender to the passenger door jam and then through the boot in the door frame. Wire loom fits perfect in there and does not interfere with the door and hides the wires nicely.

You have to remove the inside passenger kick panel to pull the wires through. Once through it's a cake walk to the connector.

 

I do have more pictures if there's something you want or don't see feel free to ask (hopefully I have it). The wiring in that utility box is unique to the KC 800 Rally relays but I can explain a bit of what's if need be. Most of that info and schematics have already been provided in the link I posted.

I used a similar route except on the drivers side and went through the plastic plug.

My truck has the snow plow pkg with the beacon switch overhead. Wanting to do an LED in the lower grill opening and use that switch to power it. Good idea? Issues, concerns? That switch should be ok amp wise I think. Chasing wires down and running to the front of the truck will be the hardest part.
