This taillight type of VNA2 / VBA1 and late GS150 models (VS4-5) was the first Vespa rear light with a separate chamber for the brake light. It's Cadillac style and curved shape fits perfectly to the smooth shape of all classic Vespa. With some small modifications it suit also to later frame types, like Rally, Sprint or P-Range (possibly new holes in frame necessary).
One-piece cast aluminum housing with inserted plastic lenses.
Very high-quality original SIEM rear light!
Delivery without seal to the frame, without bulbs
