Alla Lighting Newest W21W 7440 CANBUS Decoders for Anti Flicker Turn Signal Lights

This listing offers a pair (2 pieces) of W21W 7440 CANBUS Decoders designed to address the issues associated with installing LED headlight bulbs/DRL lights on most European vehicles. These decoders are designed to solve problems such as flickering, error codes, and non-functioning lights that can occur when LED bulbs are used, as they draw much less current than the stock lamps.

The key features of these CANBUS Decoders include:

• Directly plug and play, providing an easy installation process.
• Able to solve flickering, error code, and non-function problems on most European vehicles.
• Cancels error messages caused by the On-Board Computer (OBC) Check.
• Permanently resolves the annoying LED beam flickering problem.
• Includes 2 pieces of W21W 7440 CANBUS decoders per order, each with a single filament.
• CAN Bus Error Free for T20 wedge LED bulbs, preventing hyper flash/fast blinking.

Please ensure that the female plug on the decoders matches your stock harness before purchasing. The installation process is straightforward, with an average time of 15-20 minutes.

These CANBUS Decoders are designed to solve the problem of LED bulbs flashing/flickering or generating error codes when installed. They feature an extension cable length of 29.5 inches and can be used to upgrade halogen/incandescent front/rear turn signal blinker lights, backup/reverse lights, and brake/stop/tail light lamps to LED bulbs.

The CANBUS Decoders are compatible with a variety of standard sockets, including 7440, W21W, 7441, 7440K, 7440KX, and 7440LL, but are not compatible with CK-type sockets.

The manufacturer offers a one-year warranty and lifetime support for these CANBUS Decoders, ensuring customer satisfaction and peace of mind.
