DISCLAIMER: These products are not approved for use on public roads. On-Road use will lead to cancellation of operating license and loss of insurance coverage. It is in your own responsibility to comply with local legal requirements. Not for sale in USA/Canada for High Beam/Low Beam.

Special heat dissipation: The Retrofit bulbs are equipped with a built-in motor fan and a high-quality aluminium heat sink with anodized coating, providing a large radiation area. Thus, the heat can be dissipated effectively, reducing the danger of overheating, and ensuring an optimal brightness at any time of operation.

The Retrofit bulbs work for both 12V and 24V applications.

The innovative brand new all-in-one bulb design includes an integrated driver box, offering multiple advantages. The constant current driver prevents overheating by automatically dimming at high temperatures. The compact driver box provides more space for the bulb body while the centre ring facilitates easy fitting.

Issue: Dashboard error message lights up
May occur in: Cars with bulb failure detection
Reason: The car's lightbulb failure detection system is designed for halogen bulbs with the corresponding high wattage. However, LED lamps operate at low wattages. When the fault detection system detects low wattages, it reports a defective lightbulb.

Solution: The threshold of the bulb failure detection system must be adapted to the lower wattage of LED bulbs (CAN Bus). In this case, a CAN BUS adapter must also be installed.

Issue: flickering and dimming
Can appear in: Any type of car
Reason: The error is caused by pulse width modulation (PWM) in the power supply to the car's headlights
Solution: LED light repair CANbus adapter must also be installed

Issue: No light
May occur in: Any type of car
Reason: Some LED bulbs are polarized (+/- pins). If the bulb, i.e. the pins are inserted reversed, the bulb will generate no light.
Solution: The LED bulb must be removed and inserted the opposite way.
