Can I change the LED to make it a different color?

Asked by: MY1PATH
No you cannot. The Ford Factory Match features internal white LEDs that cannot be changed. Special material in the dial creates the color that matches the factory Ford lighting.

Can the color of the backlight for this gauge be changed to red? I have converted the dash of my 1997 Ford F-350 to red backlighting and I'm looking for gauges to match.

Asked by: Fairlaneguy
We are not able to change the color of the lighting on this gauge due to the way it is manufactured.

If I already have all the wiring, is there any way I can just get the gauge itself?

Asked by: spencer1
Thank you for your question. Unfortunately, the gauge head is not available by itself. You can only purchase it with the sending unit and wire harness as well.
