Head lights on and off

[-=JoN=-]

Happened like 6 times already, in 4 separate occasions...well, it happens in 3's

driving down in the highway, the lights would just turn off, then back on.....as in all lights, dash, head lights.....

usually happens once...then a bit later it will happen two times a minute apart.....

i have a new battery in there.....alternator?

have your alt checked

have your gauges also been dying at the same time, or is it only lights?

The headlights and all turn off? I bet thats scary at night! Do the fogs go all also? Im going to guess the stalk or the BCM.

My dash lights would go to BRIGHT if I had them dimmed then back to dim, but that stopped along time ago. Ive never had the headlights go off though.

Jon........you could take it to Advace Auto and they will test the alternator for free if you don't have a tester.

i had a 70 something nova that the headlights only would come on and off, turned out to be the dimmer switch.

my wifes interior lights blink on and off from time to time. I am thinking a door switch is faulty but haven't tracked it down yet.

yeah, dash lights on and off too...(as if i was turning it on and off from the stalk) ...also need to replace some bulbs in the dash, but thats besides the point....

gotta figure out where theres an advanced here....

tnx

Additionally, Something I have been hating so much, the Fogs Blink when the Clicker flips back into place after I complete the turn. You know, the blinker arm swings back into place, darn fogs blink when this happens.

Seems to be a KJ thing. Replacing the multifunction switch fixes it but for some reason, only a while. Mine does it too. 9.5 times out of 10, the fogs blink, but the other .5 times the headlights blink.

Hmm, Ive never had my fogs or headlights flash. Im glad Ive got my hellas incase the crazy headlights do decide to go off! Nothing like a good old switch, relay, and direct wiring!

Advance....Autozone.....maybe even Napa....I think just about all of them will test an alternator or battery.

I had it happen on my old ZJ, but only the head lights. Since the headlight switch tested OK I traced the wires into the steering column. I found that the wire that plugs into the hi-beam switch had worked itself loose. (probably from tilting the steering wheel) Pushed the plug in and problem solved.

...so, maybe just a loose wire?

Bad ground in the head lamp/Day time running lights circuit?
Trouble shoot the fuse block.
Check to see if the headlamp switch connector plug makes a good connection and that there are no loose male to female connections within the plug.
Failing that, I have a few Lucas Prince of Darkness wiring looms I can give you!

j/k

Ry,
