If your headlight lid goes down then pops back up it is most likely a missing bump stop (insulator).
Here is a topic on the C5 forum.
GM part number 16524060. Headlight bump stops. No longer available from GM.
Reference the TSB page: Bump stop TSB page. This is for the drivers side only.
Special steel spacer washers. GM part number 11505463. I had these steel spacer washers made and these steel spacer washers are now included in all my C5 headlight gear kits! NOTE: I also had these steel spacer washers made in a better size to match the bosses on the headlight motor. The GM steel spacer washer is very large. My steel spcer washers are about the same size as the bosses on the motor making them almost invisible when installed.
7-25-2013: I now have these in stock! See a write up on the Corvette forum:
|The inside dimensions are exactly the same as the GM originals
||The outside dimensions are exactly the same as the GM originals
|Another view next to a GM OEM bump stop. My reproductions are the same as the GM originals. A tough slightly soft high impact plastic material.
||They fit snug on the steel brackets just like GM OEM bump stops do.
These are made from the same type of plastic GM used. Others in the market place are made from a brittle plastic and do not last!
Set of 4: $11.00

Shipping: Shipping in the USA via First Class Mail is $5.00
Shipping to areas outside of the USA: Generally I ship postal air first class mail. Shipping varies depending on what country they are going to. It ranges from $11.50 to Canada to $18 or more to Australia etc.
I do not offer free shipping.
Because I use postal flat rate boxes for heavy orders there is no program that can add the proper amount of shipping to every order. So all shipping is added manually by myself after you place your order. That is explained here: Shipping added later explanation
When you place an order the shipping amount will show $0.00. Soon after you place an order you will receive an email confirmation that shows the amount of shipping that was added to your order.
