Red reflector (57111)
A red fender-mounted reflector for Triumph, catalog number 99-1030, later renumbered 57111T.
This is a red reflector that mounts to the fender on a Triumph, catalog number 99-1030, also known by the Lucas-style number 57111. It shows up in the parts book under the MUDGUARDS (FENDERS U.S.A.) and FENDERS figures, so it's a fender-mounted item rather than anything electrical, even though the number pattern looks like a Lucas part.

Our catalog record only ties this one to 1969, and it later carries forward under the number 57111T once the factory renumbered it. If your parts book lists 57111T instead of 99-1030, you're looking at the same physical reflector.
These are small, easily lost or cracked pieces, so it's worth checking the lens and mounting hardware on your fender before assuming the reflector itself is the problem. Call the shop if you want to confirm which fender position this one goes on for your bike.
