Lights Flicker
I did a search and only one instance of this was found with no resolution so here we go......my daytime running lights (and to a lesser degree my headlights..when on) flicker. I don't have to touch the gas, they just do it by themselves. Now to muddle the picture even more, I've recently installed 4 off road lights. 2 I've tapped into the right front parking light so they'll go on with the parking lights, the other 2 I've tapped into the gray high beam wire on the right headlight so they;ll go on only with the high beams. Neither of the off road lights flicker though!!! All the grounds look solid enough and I've attached the power lead into the battery itself.
Frankly I'm baffled. I'm considering unhooking all the additional lights to see if that's the problem. But if someone here can offer any other advice, I'd sure be glad to listen!! ...could it be a bad battery or alternator or can the problem be a result of the additional lights???? Beats the hell outta me! :(
Thanks guys.

I don't know what the answer is but if it was your alternator then it would be affecting your offroad lights as well. I'm no expert but I do have alternator experience from my loud stereo days.

Got a new symptom this morning. When I start the Jeep now, the lights wired to the high beams come on very dimly for a second then go back off again. I suspect they may be the culprit causing the problem. I'm wondering if (since they're tapped into a headlight) if they're causing a voltage drop.....but why now though??? They've been connected for over a month.
Hmmmm.
Hmmmm.

you could always try getting a relay harness and running current directly off your batter for your head lights and how are your off road light wired in?
On a seperate note, I disconnected and reconnected the relay and now the off road lights don't fade on and off when I start the Jeep. Could it be a bad relay? But is so, why do the headlights still flicker when the relay was disconnected??? Man, this is driving me crazy!!!

I thought it was. I used a round wire terminal and screwed it onto an existing ground wire set on the side of the inside fender. Should I ground it seperately? Would that cause the symptoms I described?....especially after running fine for weeks. ???

I got this advice from another source:
Any thoughts/comments? It sounds feasible.
bad idea tapping them into the headlight circuit to power anything
JKs use pulse width modulation power for the headlights.
it reads the resistance and pulses the power to the lights, by adding the extra draw, you've probably confused the hell out of the CANBUS and its pulses are way off causing the dimming effect.
its probably not as apparent on the off road lights since you probably grounded them directly, which is gonna confuse the headlight circuit even more.
I'd whip out the sonic screwdriver and yank em real fast before the computer takes real exception to it and blows itself up or something.
