As to parking lights for 1931-1935 models, did the lens change at any point (e.g., to an elongated version like the tail lamp lens changed for 1935 models?) or did H-D just start referring to the lens as a beehive lens at some point after 1931? I see parking lights listed in the 1931 accessories catalog under "New Bullet type Parking Lights" with a lens that appears to be a beehive-type lens (that projects "ahead of the lamp body approximately one-half inch"). I also see parking lights listed in the 1935 accessories catalog with a "beehive lens." But, I don't know what happened, if anything (as to the description or mechanically), in between 1931 and 1935.
