Pair DRL Warning Canceller Diode Dynamics

Some vehicle manufacturers, such as BMW and Audi, use alternating current on new vehicles to extend the lifetime of halogen bulbs.

This is often the case on DRLs to achieve a lower brightness level during the day.

Specifically, this is called Pulse Width Modulation.

HID conversion kits require continuous current to operate correctly.

If HIDs are installed onto a DRL circuit, the lights will flicker very quickly when the vehicle is turned on.

If you have a relay, it will buzz loudly.

The solution for this is the Warning Canceller Module.

The HID Warning Canceller Module is also known as an HID Error Message Canceller, HID Decoder, HID Anti Flicker Capacitor, or Canbus Killer because it will eliminate bulb out or bulb failure warnings in most Mercedes, BMW, Audi, VW, and other cars when HIDs are installed.

Features prevent flickering and bulb out warnings on many vehicles when HIDs are installed.

OEM connectors allow for simple plug-and-play installation.

What's included: Quantity Two (2), 3 year Return Policy, 30-day Return with no restocking fee, 100 percent Satisfaction.

To install, simply plug the Warning Canceller inline between the signal wire coming out of the headlight and the relay.
