It uses 42 yellow LEDs for bright, instant illumination, drawing only 0.42 amps to reduce strain on the battery and alternator. The sealed polycarbonate housing and lens with a gray flange mount withstand shock and vibration, while the Fit 'N Forget stainless steel connection simplifies installation and resists corrosion. Typically replaced when a turn signal fails, becomes dim, or is physically damaged.
