So, being old and blind (slight exaggerations), I often find myself having a hard time seeing the side dots on the edge of my fingerboard, especially when there are red lights on me. Years ago, I had glow in the dark star stickers on the Modulus I was using. I couldn't find any for a reasonable price, so I thought about maybe dabs of glow in the dark paint... While searching for that at Hobby Lobby, I came across a sheet of iridescent peel and stick material. Kind of like the dashboard of a Trans Am, or those peel and stick letters you can use for For Sale signs or whatever. Bought it (under 3 bucks) and took a hole puncher to it to create dots... Works well! I know there's no way some guys will stick stuff to their Ric (can't blame ya), but I think these will serve the purpose well!
The ones at the 12th fret look crooked, but that's just the light...
