September 2011 Randys Electrical Corner - Jp Magazine

Somehow I have gotten some kind of reputation in the off-road world. I’m not sure what that reputation might be, and maybe I don’t want to know. What I do know is that when a company calls me up and asks if I want to test new LED driving lights, I am all over that.

You guys know all about me and loving LEDs. No filaments to break and if they are mounted to the circuit board right they are dang-near shock proof. If you seal the housing correctly, they are also waterproof. Truck Lite has been testing over 100,000 LED headlights with the U.S. military for the last four years and recently released a 12-Volt version for us to use. As you might imagine, the Hummers and other military trucks have been all over the world, from Alaska to Afghanistan and loads of other places, too. These lights have been tested in some of the harshest environments around.

I went with the driving beam and integrated mount, but the two-piece mount and the other beam patterns all mount up the same. The lights will work from -10 to 70 degrees Celsius. For you normal people, that is 14 to 158 degrees Fahrenheit. I find it hard to believe that they won’t work below 14 degrees, but since it only got down to 30 since the lights have been on the Jeep, I have no way to prove it. And, no, I am not putting the Jeep in a freezer.

So, I really wasn’t sure what I could do to them that hadn’t already been done by the big green machine. I guess it’s kind of like when Joy would give me money to get ice cream. I didn’t care why she wanted me out of the trailer, I was only too happy to go. So, I agreed and a shiny new set of lights showed up at my door.

These driving lights are basically the same LED headlights that have been torture tested all over the world but all 10 LEDs come on at once. They are available with integrated or two-piece mounts and choice of spot, driving, or fog beam patterns. I didn’t have a Jeep to put them on, but I happened to know a teenager who just got a ’97 Wrangler and figured if a teenager couldn’t break them, they were going to be good to go. So far they’ve been on the Jeep for a few months now with no problems whatsoever.

So I first tried to hook black to ground where it belongs and put the white to positive. The lights didn’t even come on. LEDs will only let power flow one way, and if you get it wrong they just don’t work. So for these, black is positive, and white is ground. It is possible that I got an early set and if you bought a set today the wires would be the colors you’d expect. The LED lights (on the right) are only rated at 1,500 lumens, and I was worried that wouldn’t put enough light down the road to really be used as an auxiliary light. However, they put out plenty of light and work great for a driving light. You can see here how they compare to a 50-watt, 6-inch-diameter HID light. The housing of the lights is aluminum with an e-coated gloss black finish, and the lens is a UV-resistant polycarbonate that won’t yellow over time and resists chips unlike many glass lenses. The Jeep already had a hole cut in the dash for an illuminated switch, and even though the lights draw only 4.5 amps, I couldn’t bring myself to skip putting a relay in the harness. Honestly, you really don’t need a relay if your switch is rated for 5 amps or better, and most automotive switches will have no problem handling the power these lights want. This is how I wired the lights up.
