I have wanted roof-mounted rear lights to provide better notice of hazards and my intentions to drivers following me, whether on the trail or highway. It's taken some doing, but I finally have a solution I'm very pleased with.

KC Hilites sells a 28" light bar with 6 LED modules of Red, Amber, and White (the race version includes blue as well, not a good idea for road use). The modules are very bright and capable of strobing, and this makes sense because they are made for emergency vehicles. KC is packaging and re-branding parts from Feniex, a US manufacturer providing lights for public safety. I was initially disappointed when I opened the box and discovered the Feniex logos, but after researching their site and product positioning I think it's the right thing to do. Feniex has many different options and control schemes, and it's more than a little confusing for a layperson. I think it would be possible to build a system with standard parts, but KC has already done the work and it doesn't apparently cost any more.

I installed a Rhino Rack Pioneer Platform, in large part to mount lights all around my Jeep. I am trying to keep a low profile, resistant to low-hanging branches on the trail, so the lights are mounted below, or in case of my front light bar, just in front of the platform. Mounting the KC chase bar is a little awkward. M4 holes are threaded in the ends, and there is a T-slot for bolts in the rear, but no brackets were provided. I probably couldn't have used them anyway. I used some 90 degree brackets from the hardware store and attached to the bottom T-slot of the platform. It turned out that it angles down slightly, so I may improve on this solution to get a horizontal beam.

The bar comes with a ~6ft cable attached. There are many conductors, I presume for each of the modules and perhaps to do some flash patterns. However, KC provides a separate controller module, so only power, ground, and two digital signal wires are used. Rather than providing a control panel for the module (which I would be interested in!), the module has many signal input wires, which you can connect to switches to tell the controller what you want it to do. So the owner decides what functions they want and connects those wires to their own switch mechanism. These are signal inputs only and draw negligible power, and don't feed back into the circuit they are connected to, so tapping into existing vehicle circuits is practical.

For taillights, there is an input to dim both red modules at the same time.
For brake/turn lights, I connected each red module's full brightness input to the corresponding brake/turn wire on the Jeep.
These three connections I tapped into the harness behind the right side cargo panel, which is wired to the trailer connector. I used positap connectors to T into the factory wires. I feel this is less intrusive than cutting and splicing, and still a very good solid connection.

To control other functions, as well as a light bar and pods, I installed an auxbeam 8 output switch panel. I use one output to power on the lightbar and controller (leaving this off disables the light bar). One output activates alternating yellow lights, an amber caution beacon. Another output turns on the pair of white lights (I have bumper mounted lights wired to my reverse lights). And I have two outputs for traffic directors - a sequence that encourages traffic to pass or merge left or right, or by activating both does a center-out pattern.


There are many other options, with some configuration for flashing speed and patterns. However I'm trying to keep it as legally justifiable as possible. My intentions are that if I am on the side of the road, I can provide notice and encouragment to other drivers to make room. I'm a truck driver and find myself working inches from vehicles traveling 75 MPH on an all too-frequent basis.

I put a Diode Dynamics 30" amber light bar on the rear of my JL using their hinge mount kit for similar reasons. It's a static light but I really like the way yours is configured.

Nice work!

I had dedicated chase lights on the last rig, and used them frequently on road. Road hazard? Lights come on to warn drivers behind me. Whiteout conditions? Lights come on to make me visible. I found myself using them quite often, and once you have them it really starts to feel like they should be standard equipment. It's an easy way to add safety for yourself and others.

I have to know how you routed your wiring for your bar. Did you come out around the back glass, or penetrate the hard top with a bulkhead? I've considered adding area lights on my tent, and potentially another set of dedicated chase lights. I just haven't found a solution for wiring that I'm in love with.

Here's some more pictures of my install. To pass the cables through the roof I used a seaview multi cable seal

The location I put it is over a single layer of fiberglass, be careful where you place it so you don't have to pass through two layers. This spot also allows the cables to follow the sport cage down into the side panel.

Clean install ? I like that bulkhead, might have to bite the bullet and do something like that.

Here's what the wiring looks like. Since I have built a rear platform for my 4xe, I have an extra 3" high floor area for wiring distribution. The KC Chase bar controller is provided signals from the trailer tow wires behind the right side plastic cargo panel, as well as from Auxbeam 8-way switch panel. Threre are a million extra wires from the KC controller that are bundled up and secured to the side.

I was looking to install the Diode Dynamics 30 flood light to use for camping. I like the multi use of this but was wondering just how good is the flood lights in the middle? I want to be able to really light up the camp site. The one pic of the flood light doesn't seem to light up the ground light your side lights do

thanks

They are all equally bright, the whites might even be brighter than the others.

I absolutely do use them for area lighting. But the lenses on all the lights have a pretty strong bias toward being a spot, intended for following cars. So they don't have a very diffuse light, and can be annoyingly bright.

There is not an option to dim the center white modules, like the outer red modules have a dim input for tail lights and another for stop/turn that is full brightness.

Great for getting attention and reverse lights.

Thanks for getting back so fast. Probably will go with the Diode Dynamics for more of a flood light.
But I really am waffling between the 2.
Got a few days until payday so will think on it

thanks again

Hi Bub,
I am pretty intersting with your KC chase lighting functions, I bought the light and the switch panel as well, I am researching the wire digram, I have a question is once I connect the KC light trigger wires (Function wires) to switch panel positive pole, do I need connect the negative wire?I saw you connect 4 or 5 trigger wires (4/5 funtions) only on posotive sides. So leave the negative side as blank?
Hope you can help with it, thanks.

Yes, the functions only need a voltage to trigger them. The controller already has its own power and ground. So you'll choose the several functions you want, and you'll have a bunch of trigger wires leftover to bundle and set aside.

Also, the chase bar itself is similar. You'll only end up using power, ground, and a pair of communication wires. There are a bunch of other wires in its cable that won't be used, either.

I have one switch panel output to turn both the controller and light bar on with a 15A fuse. Then I have each function trigger set with lowest A fuses I could find.

I also tapped into my trailer light wiring harness to provide marker lights, left turn/brake, and right turn/brake.

Here's What I used for my controller functions:

KC Controller Input
1Marker lights (brown)
5Left Turn/Brake
8Right Turn/Brake
4Amber alternating (strobe/hazard)
2White lights constant (reverse/flood)

28Traffic Advisor Right

Hi Bub, Thanks a lot for you to share the detail wiring digram. I still waiting for my KC delivery. You mentioned connect turn signal (#5 left & 8 right )/brake(#5&8)/reserve(#2) wire to jeep tail light on the PASSANGER side? So thats means connect #2&5& 8 to one side tail light wire, both sides light will work?

The wires for all tail light signals are behind the plastic wheel well cover on the passenger side of the cargo area.
