Frequently Asked Questions

Match the bulb or LED to the gauge brand, socket style, voltage, and physical size. If you are changing from an incandescent bulb to an LED, check polarity and dimmer compatibility because not every gauge or socket handles the conversion the same way.

Covers and filters change the appearance of the gauge lighting; they do not change the gauge reading. Match them to the bulb and gauge style, and remember that some filters can reduce brightness.
