A notable effect of installing my new crash-bar skid plate was that it blocked some of the light from my rock lights. Prior to the installation, I’d simply had the lights mounted to the bottom of the front bumper. But, the skid cut off the forward throw of the lights, so a change was in order.

Moving the three forward lights necessitated only minor rewiring, as two of the three had to be cut out of the wiring series to free the bumper for removal in installing the skid plate, anyway. So, I took advantage of the necessity to adjust the position of all three for the best possible light throw.

Two of the three now reside under the forward frame rails, where they do an admirable job of casting a nice squared-off light below and in front of the Jeep. I placed the third on the flat plastic shroud beneath my radiator. Here, it helps augment the frame-rail lights, and also casts a little more light backward along the center-line of the vehicle, an area that had been more shadowy than I’d liked.

Overall, I’m very pleased with the new light pattern. I think it’ll be a useful change. I was a little hesitant regarding the radiator-mounted light, as I’m not sure how any heat transferred from the radiator will affect the 3M tape holding the light in place. Time will tell, of course, but it’s looking good so far. I’ve already had the chance to put them to use, and they performed very well.

My wife was a little under the weather last night, and I got off work late. Naturally, that’s a recipe for dining out. As we were leaving, I noticed the building’s blue and red neon, which I thought would make a nice backdrop for Smokey’s new accent lights, which I received for Father’s Day. It’s just a phone shot, but Photoshop helps a lot. Kinda fun, don’t you think?

Lighting the trail: Installing GenSSi rock lights

UPDATE:  Since this write-up, I’ve added some color accents and moved my forward lights. Click here to see that write-up.

As promised, here’s a belated write-up on my recent rock-light installation.

Like a lot of things in life, it all began with an impulse. I’d gone to the state fair with some friends, where we found a vendor selling LED lighting at pretty decent prices. Rock lights already were on my future-modifications list, so I engaged the fellow and made a deal. Naturally, that was when he informed me he didn’t actually have the lights in stock at the fair and, if I’d leave my contact info, he’d be in touch.

Never one to sit around, I started looking online to compare options and pricing. And, about the time I decided to give up on a mod that might see limited use, I stumbled across a YouTube video in which a fellow Jeeper was showing off his new rock lights. The lights in the video were bright, used name-brand LEDs and were incredibly cheap, so cheap, in fact, that I could get 12 lights and a switch for less than eight of the no-name state-fair lights.

Materials/tools needed:

  • GenSSi rock light modules w/wireless switch and controllers
  • Black automotive-grade silicone
  • 18-gauge wire (black-insulated)
  • 18-gauge wire (red-insulated)
  • Heat-shrink electrical butt connectors
  • Heat-shrink sleeves
  • 3/8-inch plastic electrical conduit
  • Electrical ring connectors
  • Self-adhesive cable-tie base
  • Cable ties
  • Electrical tape
  • Wire strippers/cutters
  • Heat gun or cigarette lighter

Step 1: Plan LED mounting positions and wiring method/route

PlanB

Akin to the carpenter’s mantra, “measure twice, cut once,” careful advance planning is the best way to achieve a satisfactory light coverage pattern.

I initially considered mounting two lights each at the front and rear of the Jeep, two on each side and one each in the fender wells. A couple of things changed my mind.

First, I’m seriously considering one day moving to a set of aftermarket fender flares, and I don’t relish the thought of repeating my work on these lights, if it can be avoided. Second, my early tests using a darkened garage and a nine-volt battery suggested there were more optimum lighting locations than the fender wells.

In total, I conducted five pattern tests using my iPhone flashlight and, later, the rock lights themselves, ultimately settling on three dual-LED lights to each side of the Jeep — port, starboard, fore and aft.

Step 2: Waterproof the lights

The GenSSi LED lights claimed factory waterproofing, but since the heat-shrink wrap didn’t quite cover the wires’ entry point into the lights, I chose to apply some inexpensive silicone insurance. A quick smear of black automotive silicone on each end took care of the problem, but required 24 hours to cure.

Step 3: Clean the mounting locations

IMG_5581If these GenSSi units have any downside, it’s that they use 3M tape for mounting. Each light does have a small hole at each end, but these would be best-suited for indoor nail-affixed mounting, due to the small size of the holes.

That being the case, I took great care to fully clean the surfaces to which I’d be mounting the lights. I started with a soap-and-water mixture, then followed up with an alcohol wipe and fully dried each surface.

Step 4: Mount the lights

Peeling each protective cover off the double-sided tape, I placed the 12 lights along the underside of the Jeep, giving each one a strong push in the middle and at each end to ensure a secure bond.

Step 5: Wire the lights

Had I to do it over again, I’d have saved a great deal of time and energy by connecting my heat-shrink butt connectors on one end of each light before mounting them. Instead, I spent the majority of my Saturday on my back under the Jeep stripping, connecting and weatherproofing wire, followed by wrapping the whole installation in appropriate loom.

Step 6: Connect the switch and battery

Having run the lights in parallel, I wired up the lights over the right front wheel to the wireless switch (a temporary solution until I’m ready for an sPOD), and the switch to the battery. After “teaching” the switch to recognize its remotes, all that was left was cleanup!

First impressions

I’m very satisfied with this solution, and I’m glad I chose this route over what would’ve been just eight lights under my original plan. The finished product gives me plenty of light along the sides, rear and underside of the vehicle. Additionally, I anticipate the rear lighting pattern to be even better once I jettison the factory rear bumper in favor of a shorter steel replacement. As expected, the lighting at the front could be a little better, but I didn’t want to place lights where I’d be ripping them out again in a year or two when I replace these fenders. Instead, I’ll add two more lights when it’s time for the fender swap.

Total time to complete

Working amid interruptions and distractions, I divided up the project over an entire weekend. Taking my time, I’d estimate the total project took me about four hours or so of actual work time.

$47, plus incidentals

Rock on — at night, even!

To date, I’ve not done any night wheeling, in part because I’m not outfitted with anything other than Jeep’s anemic factory lighting. That’ll change this weekend, however, with the arrival of my GenSSi rock lights!

These dual-Samsung 5730-chip LED lights put out 100 lumens each, and at only 1.2 watts. (In an initial test using a 9-volt battery, just one of these lights lit up an entire room, albeit dimly.) I opted for 12 of the lights, controlled by a wireless switch that will mount under the hood. Eventually, I’ll hardwire them to my planned sPOD, but for now, the wireless option is significantly cheaper.

Watch for an install post in the coming days!
