Yes, most likely. There's a chance that it is something mechanical, but that's a slim chance and only if they have not been used in a LONG time.
If you're not familiar with these problems, I suggest chasing the vacuum lines to listen for a hissing sound either underhood or under dashboard. Remember that the headlight switch actually is an electrical switch AND vacuum valve in-one. Additionally, there is a little black knob (backup vacuum valve) directly under the dashboard in the event that the headlight switch valve doesn't raise the lights. If neither one raises them then you have either a leak or stuck diaphragm. Good luck! -ku2002
You can buy a vacuum troubleshooting guide from Zip Corvette to help you fix the issue.
I fixed it. There are rubber devices called witches hats that go on the vacuum canisters next to the headlights. You can either change the witches hats (quite a job) or just have the vacuum canisters you can get at Ecklers.
Or you can get them at Zip and save some money, here is a link to the headlight components http://www.zip-corvette.com/Zip/dept.asp?dept_id=887where is the diaphragm located on my 1981 Corvette?
check vacuum lines to canister,light switch,check valve, Accuators
Should be located just in front of the radiator near the headlights. One on each side.

what could be pulling the battery down in a 1981 corvette
They are compatible. the only problem you may have is the shifter. If the corvette does not have overdrive on the shifter you won't be able to get the car in first gear.

There is no computer.
You can find reviews on a 1981 Corvette online at the CarGurus website. Once on the page, click on "Research" in the top navigation bar, then choose Make: Chevrolet, Model: Corvette and Year: 1981 to bring up the reviews.
The "Stingray" moniker was not used in 1981.
The headlights and the tail lights may not be working on the 1981 El Camino because of a mechanical breakdown.
1976 top will not work on an 81' The latches are different.
The 1981 Corvette was built in St. Louis, Missouri, but half way through the model year Chevrolet moved production to Bowling Green, Kentucky.

There are vacuum lines in your ignition switch. One of them is leaking or had been pulled loose. If the former is the problem, replace the vacuum line.
Yes. Although the L-82 engine was not a Corvette "option" in 1981, I've seen at least one 1981 Corvette with an L-82 motor and that option code was clearly listed on the window sticker. I'm guessing Chevrolet used up the last of its L-82 motors in early production 1981 Corvettes. It did in at least one anyway.
Supposedly, a 1981 Vette does not have an L-82 engine. It has an L-81 engine.
check to see if the glove box light is on.
