James: Please tell me how you would eliminate the dark red plastic that is underneath our grey gauge faces and I will believe you.  What colour bulb + red = blue?  I am VERY skeptical that this works on our cars.  Dave F.

Hello Dave F., with respect to "There is no way to get blue light", I beg to differ...

Dave:  I think you will find that the plastic that looks makes the numbers look black in the daytime and red (okay, orange) at night is, in fact, very dark red plastic.  The IC is back lit, not side or top lit.  Hence the colour change from black to red at night.  There is no way to get blue light.  White bulbs = orange lettering at night.  The only way to get redder would be to have coated bulbs or use red bulb "condoms" (like you get when you buy an AutoMeter Boost gauge).  Or LED's.
