Bixenon HID Adapter H4 Pair Diode Dynamics Ferrari protecting the internals from moistureWhen installing HIDs in a dual filament application, the original factory power signal must be separated into main power for the ballast, and a high beam signal to trigger the bixenon bulb, switching from low beam to high beam. Normally, this is accomplished with a bixenon relay, which connects to the battery and runs to each headlight. However, these can be unreliable as the relay fails over time, and cumbersome to install. These bixenon adapters are
