Headlight warning beeper

[Bob Murray]

the headlight warning beeper is beeping whenever the key is removed from the vehicle. It beeps all night, it is beeping right now. I'm wondering if anyone has an answer to why or a wire to cut that will shut it off. It has done this sporatically for awhile, but now it is 100%

Sometimes the headlight switch can get stuck or malfunction. Try turning it on and off several times to see if that resets it. This would be my first guess.

In addition, check for any damaged ground connections, as they could cause intermittent issues. Making sure all connections are tight and clean can sometimes resolve bizarre electrical behaviors.

If you need a quick fix, you can locate the beeper and unplug it.

I’ve actually done this mod on my TJ, and it’s a lifesaver—no more dead batteries from leaving the lights on. I tapped into the door switch and headlight circuit, then added a small piezo beeper behind the dash. Super simple, took maybe 30 minutes, and cost next to nothing. Should’ve come from the factory like that honestly.

I swear we already have this, but I think most people remove the fuse so that their interior lights aren't on when the doors are off. The downside is you lose the buzzer. This is how my 2000 TJ was, I'm almost certain.
