Socket Base Vehicle Headlamp Light Bulbs


Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

LED Light Bulbs for High-Intensity Discharge (HID) Lights


Replace high-intensity discharge (HID) lights with the longer-lasting, energy-efficient LEDs. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. LED lights are perceived as brighter at night than high-intensity discharge light technologies, so they require fewer lumens to provide the same brightness. Match your old light’s wattage to find the right LED bulb. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh.
Ballast bypass bulbs eliminate the need for a ballast, so the socket must be wired directly to the power source.
