I was poking around on the Internet one day and I saw someone with "rock crawling" lights. Now I'm not interested (at least not with my XJ) in crawling on the rocks, but I thought under body lighting could be handy during the bad weather we have in Houston.

I read a bit and found that traditional rock crawling lights have a few drawbacks. One they get hot and water has a tendency to crack or break the bulbs and lenses. The other issue, also breakage, has to do with rocks or debris hitting the incandescent lights.

I happened across a website that sold LED rock crawling lights. I did some reading and found that these LED lights were bright but used 1/10 of the power required by the incandescent "traditional" lights.

The ad listed them as virtually indestructible, and cool to the touch.

I originally was going to purchase the WHITE LEDs. I thought about it for some time and went "pimp" with the RED!

So I purchased ONE to see just how bright it was. Once I received it my girls and I went outside one night. I held the connection to the battery and one of the girls held the LED under the Jeep. We looked to see just how bright it was. I was impressed, so I ordered 3 more. In addition I ordered their "switch" box. It allows you to turn the LEDs on and off or you can flash them at various rates by turning the analog dial. They call it a strobe. :D

I purchased some rubber grommets to put in the hole so the wire coming from the LED would rub against the bear metal. I also purchase some sheet metal screws with a rubber backing to attach the metal LED bracket to the bottom of the Jeep.


I drilled three holes. One for the wires and two for the metal bracket.


I positioned the four LED lights around the passenger section.


I ran all the wires in the channel at the bottom of the doors to the front drivers side.


Finally I connected the wires to the control box.

The lines were pretty short on this box so I mounted it where it would reach the lines from the four LED lights and where I could reach it.


This is a picture in the garage, with the garage lights on.



:bow:Both of these are over exposures but they are close.

Future:

This was the first, major, step. I still have four more LEDs to add. Two behind the rear tires and two in front of the front tires.

These LEDs DO NOT produce near the light that traditional incandescences produce. If you are a TRUE night rock crawler these are probably not for you, however if you would like to have light to see under your rig in very dark environments, these are great. Also you could leave these on all night and still start your heap in the morning, at least that is the claim.

You could also be very clever and hook these up to your keyless entry so they come on when you unlock the doors with the remote. This is great when you are trying to get in the Jeep. You can easily see where your feet are and where the bottom of the door is. :thumbsup:

These LED rock crawling lights were purchased from http://www.roundeyes.com/

Total project cost was about $150, and about one to two hours of my time.

Remote Keyless Entry (RKE)
It really isn't that difficult to add RKE control to your additional lights. You'll need a way to tap into the control line, a standard automotive 12 volt relay, and some wire.

If you slide your dome light forward and look under you'll see this (1998 model)


You need to tap into the yellow line, see arrow


Please NOTE that you have to switch the GROUND and not the 12 volt shown here. (I know I need to update the diagram)

The LED grounds are connected between the 87 and the chassis. The 12 volt goes to 30. I found this out as I was trying to hook my LED rock lights up. :(

The best part is the red light wont hurt your night vision, so if you have a spotter, they wont be blinded, nor will you be while using your mirrors.

Very good call, I didnt even think of that.
I started to mention the night vision thing, but that was an after thought to justify the real reason "it just looks cool". lol

I actually considered putting in a second set of RED LEDs internally. Put a switch on the dash.

I'd tell the wife, "Rig for night vision" and she'd say "Yes Captain!" and hit the switch! :rofl:

Cool idea Mudderoy.
If you look at the bottom of RoundEyes you'll see you can order in several different colors, including RED.


As you can see there is enough room in the dome light housing for two of these.



Autolumination is another excellent source for LED replacements, including tail lights. I used these people for the kick panel LED replacements.

been looking into these after a friend put some on his TJ and decided that sence we do a lot of night niding this would be a great thing to invest in.

Looks good. If we night wheeled more I might consider something like that for our rigs (wouldn't use them enough right now to justify the cost). Actually though, I've got some LED "LITEblades" that OffRoadOnly used to make that I've yet to install. The main advantage to using the LEDs is that they only use a fraction of the power that a regular halogen bulb will. And of course they're available in colors, so you be "pimp" like Mudderoy if you want. :D

We run a set of $20 Wal-Mart 'ricer' driving lights as rocklights on both our rigs. On the XJ we've got one mounted on each side on our rocker guard legs, just in front of the front spring hanger. The lens on both are cracked, but they've been working fine for years now.

Okay I found this one. This gives you a better idea of what the lights look like at night on WHITE concrete.

I bought two more red LED lights for the front tires. I'll be posting up some new pictures soon. Interestingly I saw this on Extreme 4x4 today...













Same company, same LED rock crawling lights, just green instead of red.
