Blue Instrument Panel Bulbs

There used to be blue and red 194 bulbs available at the local parts store. Ran them for a while. They just make less light (generally a good thing). I now just use the rheostat to dim the dash lights as much as possible. Other than taming down the high beam indicator, I'm not sure there's much benefit. Making everything the same color is a noble goal, and I wish you luck. Just keep preservation of your night vision the top priority.
