Headlight bulb

A dead headlight bulb is one of the most common faults a car ever has, and in most cases the bulb swaps out on its own; the complete headlight unit only needs to come off the car when the lens, reflector, or housing is damaged. Bulbs dim gradually as the filament ages or the gas degrades, which is why a car often passes its MOT one year and fails on light output the next.One working headlight halves what you can see at night and is grounds for the police to stop you, so a failed bulb wants changing the week it goes, not the month after.Replacement is due when:

• A bulb has blown outright on one side
• Light output has dimmed noticeably or turned yellow
• The glass has darkened or developed a smoky coating
• A bulb flickers as the car moves over bumps
• The two headlights visibly differ in brightness or colour

The catch is the variety: halogen, HID, and LED systems each take different bulbs, and a single model range can use three different codes across its trim levels. That turns a simple bulb purchase into twenty minutes of cross-referencing on each marketplace you try. Parthunt24 stacks used headlight bulb listings from marketplaces like Ovoko, ProxyParts, eBay, and TotalParts into a single search, so 15 options can be judged on price, condition, and fitment before any seller's page is opened.

Every bulb carries a code, and that code is the whole game: an H7 headlight bulb fits an H7 socket and nothing else, an H4 combines high and low beam in one bulb where H7 cars use two, and D-series codes (D1S, D2S) belong to HID systems with their own ballasts. The handbook or the code stamped on the old bulb tells you what your car headlight bulb should be.Technology matters just as much: halogen, HID, and LED don't interchange freely, and dropping LED bulbs into halogen housings is illegal for road use in most of Europe because the beam pattern no longer focuses correctly.Searching by make and model on Parthunt24 strips the bulb listings back to those for your car. Opening any result moves you to its source marketplace, with the seller's write-up and checkout there.

• Vehicle compatibility: Match the make, model, year, and headlight type.
• Bulb type: Verify the exact bulb code, such as H7, H4, D1S, D2S, or H11.
• Halogen, HID, or LED compatibility: Different headlight systems require different bulb technologies.
• Low beam or high beam: Some vehicles use separate bulbs.
• Wattage and voltage: Ensure electrical compatibility with the vehicle.
• CAN bus compatibility: Some LED upgrades require CAN bus support to prevent errors.
• Colour temperature: Verify the preferred light colour and legal compliance.
• Socket and connector type: Check the mounting base and electrical connector.
• Road legality: Certain aftermarket LED or HID bulbs may not be road legal.
• Pair replacement: Headlight bulbs should ideally be replaced in pairs for equal brightness.
• Condition: Inspect for darkened glass, damaged connectors, or worn contacts.

Bulbs are cheap enough that a bad purchase stings less than most parts, but a few checks on the listing still save the double order. Used bulbs lose brightness with every hour of use, so an honest note on the donor car's age or mileage tells you more than the photo does.

• Photos: Shots of the glass, filament or element, base, and pins.
• Seller reputation: Feedback score, time trading, and review history.
• Compatibility: Bulb code and connector confirmed against your car.
• Included components: Single bulb, matched pair, or with holder and cap?
• Condition: Darkened or smoked glass, corroded contacts, bent pins.
• Testing: Confirmation the bulb lit correctly before removal.
• Warranty and returns: A clear path if the bulb arrives blown.
• Shipping: Bubble-wrapped and boxed, since bulbs travel badly loose.
• Documentation: Donor car details and removal records.

Once the code and condition are both confirmed, order it straight from the seller's page.

Headlight bulb price runs from pocket change to a serious outlay depending on the technology. Used halogen bulbs open at €2-€8 each, HID bulbs sit around €15-€50, and OEM LED modules for newer cars push past €100 because the bulb and electronics often come as one sealed part.Headlight bulbs for sale appear on Parthunt24 from as low as 5.00.Why one headlight bulb price beats another:

• Technology: Halogen stays cheapest, HID mid-range, LED modules dearest.
• Pairs: Matched pairs cost more upfront but keep both beams even.
• Brand: OEM and big-name bulbs hold value over unbranded stock.
• Usage: Low-hours bulbs from young donor cars earn a premium.
• Bundles: Holders, caps, and connectors included add a little value.

Bulbs age across the whole car at roughly the same rate, so the failed headlight is usually a preview of what's coming. Checking the other lamps while you're already ordering saves the postage on a second purchase a month later. Browse these on Parthunt24:

• Headlight lens: Yellowed or sandblasted lenses waste the output of a fresh bulb.
• Xenon bulb: The HID option for cars with D-series systems.
• LED daytime headlight: DRL strips fade and fail section by section.
• Rear lights: Cluster faults often hide until a bulb check.
• Fog light bulb: Forgotten until fog actually arrives.
• Rear tail light bulb: A two-minute swap that avoids an MOT advisory.
• Tailgate light lenses: Cracked lenses let moisture kill fresh bulbs quickly.
