LED indicator bulbs with 22 SMD COB LED chips, a set of 4 for front and back turn signals on motorcycles and cars, listed for the MT 15 and R15 V4. Each bulb draws 4W and gives super bright 6000K light that keeps the vehicle clearly visible to other drivers, with an immediate response on every blink. A built-in intelligent IC driver regulates voltage and protects against current fluctuations, for stable blinking and an extended lifespan. Power use is significantly lower than a traditional halogen bulb. Each bulb has a silver metal bayonet base and a flat round face packed with SMD chips. The set installs easily in front and rear turn signal housings across a broad mix of motorcycles and cars.
