Orange reflectors that say "BSA"???

In have a Golden Pless book of "Classic & Thoroughbred" bikes. In it are two pictures of a Rocket 3 and a 68 Shooting Star and both have tail lite frames with the triangle reflectors but the reflectors are orange and have BSA lettering with the winged B on them.. I've haven't ever seen these for sale, are they a short lived item not used much? Does anyone sell them? Thanks, Glenn T.S.

I've never seen them either. I have a 68 Shooting Star with its OE tail lamp assy. The reflectors say Lucas and DOT on them.

The orange or yellow ones on mine are round and under the front of the tank.
