Headlight Pops back up when lights turned off
Good evening! I did a couple of searches but came up empty.
I recently changed the battery in my '02 c5 vert. After that I started encountering a problem with my left headlamp.
When I turn the lights on they both pop up and run as expected. When I turn off the lights the left lamp pops completely back up with the lamp off.
Has anyone run into this? Thanks!

There are, I believe four, nylon plastic bumpers (stops) on each headlight. They are easily recognizable. They can wear or fall off. They can be purchased from any of the forum vendors. Check and see if any are worn or missing. It's an easy fix

How does the stops work, not doughting u , just courious. I assume the lights hit the stops and something like a torque switch detects the increased torque and tells the light mechanisms to stop and if the stop is missing it throws the system out of sink. Is that even close to how it works? Thanks

It's my understanding (from previous threads) that if they're missing or worn, it will cause the headlamp doors to open. I've read you can pull them off with plyers and turn the over to expose the better side. They are inexpensive to replace. Hope this helps.

If the stop is missing, the headlight will slightly pop back up an inch or two. Mine did.
It typically does not pop the headlight all the way up.

Yes mine was doing the same thing I bought four of the nylon bumpstops from corvette central and that cured it. the ones on the bottom are hard to find you have to open your headlight take off the plastic shroud and feel around t the botdown in there for a square tab bottom ones are your culprit I ended up not even replacing the top two.

It happened to me on the driver's side when I first got my car (a 2000). New bump stops cured it and it's been fine now since replacing those for over a year. This is a common problem making the lights pop up.
