Converting the Lightforce Offroad Lights
into 23,000 volt Flame Throwers



For years I've used the Lightforce Offroad Lights on my 4x4 vehicles and have always been impressed by their performance and durability.  Especially so after comparing them to many other types of offroad lights I've previously bought and used, most with mediocre results.  So I've already been sold on the Lightforce brand, that's a given.  But when Dick from Offroad Lights in Washington told me about a conversion kit he developed specifically for the Lightforce lights where the Halogen bulbs where replaced with an High-intensity discharge (HID) system and Xenon bulbs I was intrigued.  He kept insisting that he was blown away by the difference in performance over the Halogen bulbs and even more so when the wattage consumption was taken into account; much less with the Xenon kit.  I have to admit, I was a bit skeptical at the reported gains but I wanted to give them a shot and try out the conversion, so I ordered up a set for my RMDL170L Lightforce lights mounted on my CJ-7.   I travel across mountain trails, many times at night and a good set of high power auxiliary lights is a huge benefit to see well on those dark nights.

I got the kit rather quickly and was pretty eager to check it out.  The kit comes with the following:

(replaces the exisitng Lightforce part)
3 feet of wiring with Extra protective nylon sleeving
2 D2S HID Bulbs
(Bulbs are replaceable)


2 HID Ballasts and 2 mounting assemblies

The installation was going to be pretty straight forward.  I'm already using the Lightforce RMDL170 'STRIKER' 170mm diameter lights, which are mounted to my CJ-7's windshield hinges. The two 2 RMDL-ARM assemblies were going to replace my existing Lightforce parts.  The two 2 RMDL-ARM assemblies have the HID bulbs mounted in them along with a good length of wire.  These wires will run to the 2 HID Ballasts.  The Ballasts will be mounted somewhere using the supplied mounting brackets.  The power that currently runs to each of my existing offroad lights will be diverted to each of the ballasts and powered from a fused and switched relay.

Before installing the kit, I took the time to check everything out and take some pictures including some controlled pictures of the Halogen lights in action in a fixed position.  I'd later take pictures in the same location using the Xenon lights.

To the right is one of the ballasts and it's mounting bracket along with the wire lead that feeds 12 volts to the ballast.

The ballast, made by Zooty, will run on DC voltage ranging from 8 volts to 32 volts with a maximum draw of 8.5 amps.  It's normal running amperage draw is 3.5 amp with an output of 35 watts per ballast (per light).  That's much better than the 100 watt drain on my system per each Halogen light.
The bulbs are interesting.  Below to the left is a typical Halogen bulb and one from my current lights.  This is a 100 watt bulb.  It's bright, bright enough to light up the nighttime trail pretty well.  Below to the right is one of the 35 watt Xenon bulbs.  These bulbs do not contain a filament as the Halogen bulb does, rather within these bulbs is is the gas Xenon and metals.  HID lamps produce light by striking an electrical arc across tungsten electrodes housed inside a specially designed inner fused quartz or fused alumina tube. This tube is filled with both the gas and metals.  The Xenon gas aids in the starting of the lamps. Then, the metals produce the light once they are heated to a point of evaporation.  As with Halogen bulbs, do not tough the Xenon bulbs.  The reason you do not want to handle them is the oils on your hands can cause the bulb to un-evenly heat and crack.
