I just replaced all the instrument cluster lights with LEDs. WoW what a difference, however all the idiot lights don't work incl seat belt warning light, door ajar light, and the brake warning light. Could I have damaged the circuit board?

Thank for posting the fix! Does the dimmer switch still perform as it should?

you had to use a circuit board for the LED's? Sorry, just trying to learn since LED's are part of my plan. I am planning to do a fade off for the interior lights.
69 and later instrument clusters use a printed circuit to power the lights and gauges. I think that is what he means when he refers to the "Circuit board".

Hey guy,

Could you share the source and catalogue number of the LED bulbs that you used??
Also, did you order a certain number of bulbs, or are they sold as a package for a "69 XR7??

Thanks,
Larry
