A 6 volt rear light bulb suitable for most classic motorcycles (and other vehicles too) which use a single bulb with twin filaments for the tail light. These bulbs are dual brightness – the low tail light function is 6 Watts and high stop light function is 21 Watts.
The bulb base is a 15mm diameter bayonet fit commonly referred to as the BAY15D type. It is sometimes also known as a 1154 (6 volt) or 1157 (12 volt) fitment. There are two contacts on the base (one for the tail light and one for the stop light function). The two pins are on opposite sides of the base (180° spacing) and one is higher than the other so that the bulb can only be inserted the correct way round.
