Audi LED bulb: H7, H15 and D1S Canbus kits for A1, A3, A4, Q3 and Q7
Replacing an original halogen with an Audi LED bulb increases illuminated distance and color temperature without modifying the headlight unit. This collection includes the most popular bases in the range — H7, H15, D1S, D2S, D3S — in Canbus versions, meaning they feature built-in resistors that prevent the "bulb failure" message on the dashboard of an A3 8P, A4 B8 or Q3.
Why choose an Audi LED bulb from Becquet Voiture?
- High-density CSP chips: a clear beam with a sharp cut-off, not a halo that dazzles oncoming drivers.
- Canbus version with built-in resistor: no orange warning light on the dashboard.
- Copper braid or fan cooling to maintain power without burning out the LED in 6 months.
- Bases with original dimensions: the beam range remains fully adjustable.
Driving at night without squinting
An unlit country road on a rainy evening, and the yellow halogen of a 2010 A4 B8 that no longer illuminates much beyond thirty meters: fatigue sets in quickly and signs are only visible at the last moment. A well-chosen LED kit restores the beam's original range for the price of a partial service.
- A 6000 K white light close to daylight, which is less tiring on long journeys.
- Instant ignition, useful for flashing high beams and daytime running lights.
- Reduced power consumption, noticeable on older electrical systems.
- A 15-minute replacement, without visiting the garage.
H7, H15 or D1S: which base for your Audi?
The right bulb depends on the headlight unit supplied with the car, not the model alone: the same A3 can have H7 halogen or D3S xenon depending on the trim level.
- H7: the most common base for halogen low beams on the A3 8P, A4 B7/B8 and A6 C6.
- H15: dual daytime running light + high beam function, fitted to many A3 8V, Q3 and Golf models from the same platform.
- D1S / D2S / D3S / D5S: replacement for original xenon bulbs, without an additional ballast.
- W5W, C5W, T10: parking lights, interior lights and license plate lighting — the pack that unifies the color tone of the entire vehicle.
Compatibility: which Audi models?
Kits available for A1, A3 8P, 8V and 8Y, A4 B7, B8 and B9, A5, A6 C6 and C7, Q2, Q3, Q5, Q7 and TT MK1/MK2. Always check the base marked on the bulb you are replacing: it is the only reliable reference.
Installation, maintenance and warranty
Replacement is done through the headlight unit's rear access panel, with the hood open, often without removing the headlight. Handle the LED by the base and never by the chip, and check the beam height adjustment after installation. Free shipping, 30-day returns.
Frequently asked questions about an Audi LED bulb
Does an Audi LED bulb pass the technical inspection? On a vehicle whose headlight unit is designed for halogen, the replacement LED is not approved in France for road and low-beam lighting. It remains widely used for parking lights, license plates, interior lights and off-road use.
Why does my dashboard display "bulb failure"? Because the LED consumes too little power for the computer. Choose a Canbus version with a built-in resistor: that is exactly what it corrects.
Which color temperature should I choose? 6000 K provides a neutral white, the best compromise between visibility and comfort. Above 8000 K, the color turns blue and the actual range drops in the rain.
How long does an LED kit last? Allow 30,000 to 50,000 hours for a properly cooled model, which is far longer than a halogen bulb that lasts about 1,000 hours.
