I'd like to do that.  Mine is Dim with a capital D.  I'll have my dash out
and apart to fix the odometer and would like to upgrade that little blue
light.  Is the blue color from a filter that covers the hole and I can just
put a bright white LED behind it?  hoping...  I assume the bulb is wired
for 12V and I will need a resistor... what value?

Thanks for any advice!
