Accessories for LED upgrade

Sometimes, when installing LED retrofit bulbs, the lower power consumption of the LED will be interpreted by the car's safety system as a failure of the bulbs. This will display an error signal on the dashboard even though the LED bulbs work perfectly. To avoid this inconvenience, we recommend using a Philips CANbus Adapter. The Philips CANbus Adapter for Philips LED HL [HB3/HB4] and HL [HIR2] bulbs connects to the car's built-in safety system to eliminate false error messages on the dashboard. Drivers can enjoy their Philips LED bulbs with peace of mind.

The lower power consumption of LED bulbs can sometimes create current variation problems, resulting in a downgrade in the LED headlight bulbs' performance. Featuring a smart 3-in-1 function, our Philips CANbus Adapter brings an additional capacitor function, avoiding flickering and light dimming issues. Enjoy the best of your Philips LED retrofit bulbs with the latest Philips CANbus Adapters generation.

Every vehicle model is different, and most don't require a Philips CANbus Adapter when retrofitting LED lights. To know if a Philips CANbus Adapter is needed for your vehicle model, visit our Philips website and check our latest online compatibility list**.
