I never paid much attention to this, but now I'm wondering.... The '69 Bees came with 2 different style tail lights. A mid model year change? I have 3 sets, 2 have 2 bulbs and 1 has 3 bulbs. Does anyone know when they were changed? And was the change from a 3 bulb to a 2 bulb or a 2 bulb to a 3 bulb? I have a '69 Bee I bought in '85 and then I bought another '69 Bee as a donor. The donor had some extra parts in the trunk, that's how I up with 3 sets of lights. I just do not remember what style came out of which. Non donor Bee is an A39 Spring Special ordered on 4-22-69. 2 bulb or 3?????

I am pretty sure the cars delivered after the first of the year had the 3 bulb lights. Government safty upgrade. The tail light is slightly different externally also.

Yeah, the later cars had the 3 bulb lights, though I'mnot sure of the date where the change was made. My old January SPD car had 3 bulbs.

As mentioned, the lenses themselves are different as well.
