Bulb Note:

Unless otherwise noted, our lights do not include bulbs, though occasionally lighting manufacturers do include bulbs in the lights. If you happen to receive a lighting product (Headlight, Tail light, parking light, fog light etc.) that comes with the bulbs, the bulbs are not covered under our warranty. Our warranty applies only to the light assembly..

    DO NOT TOUCH the bulbs- the oil from your fingers will burn into the light and foul your bulb. Clean with rubbing alcohol and a soft cloth if the bulbs do get touched.
