It is such a hassle to change bulbs in the back of the instrument cluster when they burn out. I saw LED replacement for factory bulbs and ordered a bunch of them.
But then I realized I installed a dimmer headlight switch, so that I can dim the instrument light cluster on my 1973 Pinto, which never had this feature. Do LEDs dim with decreased voltage like conventional bulbs?
If not, I can still use LEDs for the warning lights and turn signals, and use conventional incandescents for the illumination lights.
