1992 convertible TA 3rd brake light bulb
Who can identify this bulb for me. I have looked at multiple threads but none seem to be correct. This bulb is from a 1992 trans am third break light. The biggest callout I could see is it has a tail of sorts between the 2 prongs that fits into the light socket. Pictures attached. I need to replace these but have no clue where to get them or what they are. Thanks for the help.

That is the bulb you need. If you are unsure, you can call Lon and talk to him. Those are the exact bulbs that I ordered and are working just fine in my '92 TA convertible.

They're #891 bulbs.
You should be able to get replacements at Home Depot in the outdoor lighting aisle. You can use either the 10 or 20 watt versions.
