What is the best LED to use in Autometer gauges?
Autometer gauges use side lighting to illuminate the gauge face and needle. In order to light the gauge, the LED light must pass through the mechanicals in the back of the gauge, make a 90° turn around the gauge face and then light the face and needle. In order to achieve a decent light a very bright LED must be used. The only LEDs we recommend for AM gauges are our High Intensity LEDs. We do not recommend using our Perfect Match LEDs in AM gauges. If you like the look of AM gauges but want a brighter light, check out our Stewart Warner gauges.
