My Comp II LED Gauge Light Doesn't Work, What's Wrong?

Each Comp II (C2) LED bulb and socket is checked for correct operation before it is packaged so the problem is most likely incorrect wiring, loose bulb, or the bulb is installed backwards.

Make sure the white wire lead is connected to a 12VDC+ supply (verify voltage with a multimeter). The black wire lead should be connected to Ground.

Verify Bulb Is Tight
Remove the LED bulb from the socket and push the brass bulb clips closer together. Reinstall the bulb.

Verify Bulb Polarity
The Comp II LED bulbs are polarity sensitive. If the bulb is installed backwards it will not work. If your bulb does not light, remove the bulb, rotate 180 degrees and reinstall the bulb.
