Good to know. For the other lights I replaced with LEDs I tried to find ones that would still work at lower voltages. Perhaps dimmable bulbs would be more tolerant.912 /921 style automotive bulb will work I got cheap ones from amazon for my low domes. and left the high in
the cheap ones I got from amazon started flickering tho sometimes after couple months. mainly when van is shut off and voltage is below 12.2ish
Anyone know a source for the lock cores used in the exterior storage doors? Mine seems to be missing them...
Austin Hardware online also has them.
Just be glad your ambulance manufacturer is still in business! Mine is a Medic Master, which were built by American LaFrance, who went bankrupt. Thankfully, I have relay & diode technology, so I can muddle my way through fairly easily. Many of the ambulances use a V-MUX system, made by Weldon Brass. They can be complicated to work with, and expensive if you need them to change the programming.
