HEADLIGHT BALLAST FUNCTION - The ballast provides the starting voltage, regulates the voltage and current during operation to ensure consistent brightness without dimming, fading or flickering, and increases the life and energy efficiency of the lamp. Without a ballast, the lamp will burn out quickly.

NECESSARY REPLACEMENT - When a ballast begins to fail, it will often make a buzzing sound or cause the bulb to flicker. These problems can sometimes occur during normal operation, so it is important to inspect the unit before assuming it needs to be replaced.

ENSURE FIT - Please check picture,OE part number and fitment information to verify this is the correct one you need before your purchase
