BMWs and, I beleive, airplanes have red instrument illumination.&nbsp;
My paramilitary catalogs sell red filters for flashlights and such.&nbsp;
Red light does not cause as much "after image" when you look away from
it back into the dark night.&nbsp; Your eyes don't have to adjust between
dark and light as much.&nbsp;
<BR>I was planning on using some gelatin filters, <I>a la</I> stage lighting,
to change my dash lighting to red (for my nighttime missons.)&nbsp; When
I get some I'll offer up the leftovers.

<P>But, now I'm chasing brake/clutch fluid leaks <B>under</B> the dash.
