Diode Dynamics - PWM LED/HID Anti-Flicker Module

Prevents flickering and bulb out warnings after installing HIDs or LED bulbs Plug-and-play installation, no modification needed Fully waterproof and shockproof Engineered and manufactured in USA No more errors or flickering. Diode Dynamics CAN-BUS Anti-Flicker modules are designed to condition factory power signals, both by smoothing out flickering signals to the output, and by replicating the power consumption of a halogen bulb, to avoid vehicle "bulb out" warnings that usually come with LED or HID power draws. It's a redesigned, modern version of the old, generic "warning canceller." It features nonpolar function, full power smoothing, and resistive and capacitive feedback to cancel even the most tricky CANBUS systems. Plug and play installation. Thanks to their nonpolar design, these units simply plug inline, either between the bulb and factory connector for LED bulb installation, or between the ballast and connector coming from the grommet for HID Conversion Kit installation.
