    Often used in taillights, brake lights, indicators, and other vehicle lights. These bulbs have two filaments that operate at different brightness levels, with the second filament shining brighter when activated. They lock into sockets in tight spaces with offset pins on the base; one pin is slightly higher on the base than the other pin. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.
