Dual-wire Design: This brake bulb adopts a dual-wire design, one wire is used for high-brightness lighting of the brake lights, and the other wire is used for low-brightness lighting of the tail lights. This design allows the brake bulb to provide both a bright brake signal and regular taillight illumination.
21/5W Power: The power of the brake light bulb is divided into two parts, the high-brightness lighting power during braking is 21W, and the low-brightness lighting power during taillights is 5W. Such power distribution can meet the different needs of brakes and taillights to ensure safe driving.
1680 Lumens Brightness: This brake light bulb has a brightness of 1680 lumens. Lumens is a unit that measures the brightness of a light source. The higher the lumen value, the better the lighting effect of the bulb. High-brightness brake light bulbs can better attract the attention of other drivers and improve driving safety.
Quartz Glass Material: The brake light bulb is made of quartz glass material, which has excellent high temperature resistance and shock resistance. This material can effectively avoid the bulb from breaking under high temperature and bumpy conditions, extending its service life.
