HID Lights - Odd Issue

Hi Guys,
The CJ5 I bought has some type of HID conversion kit. The odd thing is when I rev the engine the lights go out. After the engine comes back to idle the lights come back on. The jeep has a brand new wire harness, new bulbs, new everything. All other lights work with no problem.

Last night when I was turning the lights on and off I heard the relays making a louder than nornal noise. I happen to have two new relays so I remove the ones on the jeep and then installed the new. The results were fantastic, the odd issues were gone. I fired up the jeep, turned on the lights, and reved until my wife yelled at me for waking up the kids. :0)

I was originally thinking of removing the HID conversion and going for OEM, but now that they are working I will move onto something else.

Its possible the electronics on the HID lights have a voltage range where they will operate. Too high or too low and it kicks off until it senses a proper voltage for a minimum length of time. I would guess, if this is the case, when you rev the engine, the alternator is outputting more voltage than the electronics can handle and it shuts down to protect the circuitry. You might get the although bench tested, and see what it puts out at high RPM, and see if you can compare that to any spec you can find for the lights.

If I'm right, a new voltage regulator could solve the problem. I had a volsvagen when I first started driving, that had an external voltage regulator. Stupid things failed like crazy. Put one in, and while testing it, it would output close to 18v at about 2500 rpm. Computer didn't like it one bit. Threw all kinds of errors and shut the engine down. Older vehicles without all fancy computers don't care as much. Might blow some bulbs or burn some fuses, but probably wouldn't do any permante damage.

OP, please don't delete when your issue is resolved, whether you figured it out yourself or not.. someone else may have the same issue. If anything, post what you found to help others. That's where forums like this are so helpful - when people post what fixed their issue!

Good point! I updated my initial posting with the original issue and solution. Thanks.
