94 accord dx, automatic.

I have a dashboard indicator between the odometer and speedometer that
shows this:  P R N D 1 2
When I shift my gear to D, the dashboard indicator would light up the
letter to show that I
have shifted to D.  Tonight, however, when I shifted the gear to D, the
dashboard indicator doesn't show it.  I can still drive normally
though.  I think a bulb has burned out.  What's
strange is that all the other bulbs seem to work, like when I shift the
gear to P, the dashboard indicator would light up P.  The exception is
with the D indicator.

I know of an auto electric shop down the street.  Is this an electrical
problem?  Or should I bring to an ASE mechanic?
