Exactly. Or use Luminlay:Changing the black side dots to white side dots is pretty easy. The trick to drilling out the old dots is to use a drill size smaller than the dot. Drill down in the center of the dot and, when you get through the dot itself, the hollow shell will kick up out of the hole. The hole is unharmed.
Use white styrene rod stock from the hobby shop. Glue them in with CA glue, gently file them flush with a fine small flat file. No need to put any finish over them.
