Sorry, no. The dash light circuit uses a rheostat. It's expensive because:
a) it has to be big enough to disipate the heat generated by the
resistance (see my earlier post) and,
b) you can't buy one just anywhere.
The lamp dimmers internals are designed to work with household AC supply. A
similar circuit suitable for the dash lights could be put together easily
(and cheaply) by the electronicly skilled for only a few bucks. Because the
car's supply is DC an SCR must be used instead of a Triac. This bares
looking into. I've often contemplated a wiper delay module for early cars
and this is another good idea I'll have to contemplate.
I will soon be removing the dash from my GT and when I do I'll do some
serious research into a suitable replacement for the dash light dimmer. I'll
report back to the list when I find anything but don't hold your breath (I
have to put the TC away for the winter first)
