FYI

I talked to Autometer about putting a bulb cover on. Evidently this tach, and probably all of them, has "microscopic" bulbs that are soldered into the board. They are not like the incandescent bulbs which we replace with LED bulbs. My option is to buy an aftermarket rheostat dimmer solely for the tach. Not going to happen.

The baby shade film came in and a quick check shows me that it will probably be satisfactory.

Thanks for the replies.
