Bullet (or nipple) indicators have been used on buses after semaphores till 07/63. US regulations made Volkswagen to stop the production of cars with semaphores sooner as the European regulations. The bullet indicator was the first step in indicator progress to create more visibility and a safer driving. Beetles for US market had also bullet indicators from mid 55 till end of oval but the size is different like the bus ones… We have now finished this base plate and are sold in pairs. The housings are available under BBT reference 0616-495 and 0616-496 and the lenses for these indicators under BBT ref 0616-490.
