That's funny; when I read the title of this thread, my mind instantly brought up that song.
Even with every bulb brightly lit, the dash-lights in my 1985 were never anything to brag about; I often resorted to shining the flash-light at whatever gauge I needed to see.
I found some little aim-able LED flood-lights at Walmart; the kind that come pre-wired to a cigarette-lighter plug.
I bought some singles, some two-to-a-bars, and a three-to-a-bar.
I destroyed one set finding out that the little lighter-plug contained some mysterious very important part of the equation.
I hid auxilliary lighter-plugs under the dash to power these LED flood-lights.
With these little light-platforms double-stick taped along that flat shelf immediately under the instrument panel, my dash is now lit up like a jet airplane.
