OEM Automotive Headlight Bulbs

Headlight Bulbs in Brief

A dim or burned-out headlight reduces how far you can see at night and can get you pulled over. BAM Wholesale Parts carries genuine OEM headlight bulbs that match your vehicle's original bulb type and output, at wholesale pricing.

See the Road the Way Your Vehicle Was Designed To

Headlight bulbs dim gradually, so many drivers don't notice until one fails. Replacing a bulb is one of the most common lighting repairs, and getting the right one matters. Your headlight assembly is designed around a specific bulb type, base, and output, and the correct bulb keeps the beam pattern where it should be.

• HID (xenon) headlight bulbs

Why OEM Bulbs Matter

Headlight reflectors and projectors are engineered around the exact position of the bulb's light source. An OEM bulb places that source correctly, producing a sharp beam pattern that lights the road without blinding oncoming drivers. Factory bulbs also match the original wattage and color, so your lights look and perform consistently. You get dependable lighting at a wholesale price instead of guessing with a generic replacement.

Finding the Right Headlight Bulb

Check whether you need a low-beam, high-beam, or combined bulb, since many vehicles use different bulb types for each. Note whether your vehicle came with halogen, HID, or LED headlights. Halogen and HID bulbs are replaceable, but many factory LED headlights are sealed and require replacing the full light assembly. Replace bulbs in pairs so both sides match in brightness and color.

Headlight Bulb Fitment Guidance

Bulb types can change with trim level or optional lighting packages, even within the same model year. Your owner's manual lists the bulb type, and your VIN confirms the exact part number. If a new bulb doesn't light, check the socket and fuses before assuming the bulb is defective.

Headlight Bulb Takeaways

• Low and high beams often use different bulb types.
• Replace bulbs in pairs for even light output.
• Many LED headlights require a full assembly replacement.
• Avoid touching halogen glass with bare fingers during installation.

Headlight Bulb Questions

Should I replace both headlight bulbs at once?

Yes. Bulbs age at similar rates, and replacing both keeps brightness and color even on each side.

Where do I find my headlight bulb type?

Your owner's manual lists bulb types for each position. You can also check the base of the old bulb or confirm the part number with your VIN.

Can I put LED bulbs in my halogen headlights?

Halogen housings are designed for halogen bulbs. Using a different light source can scatter the beam and create glare for other drivers.

Why did my new headlight bulb burn out quickly?

Skin oils on halogen glass, a corroded socket, or a moisture leak in the housing can shorten bulb life. Inspect the housing and connector when you replace the bulb.
