What size bulb does it use ? If you can replace it ?

Asked by: Gabriel775
Thank you for your question. Our Cobalt gauges have their LEDs embedded on the circuit board. Unfortunately, there is no way for you to access them or replace them. If the LEDs burnt out, you would need to send that in to us so we can get it fixed. Here is a form with the information regarding sending a product in for service:
