Illuminated Switch Cover

Amazon sells a lighted switch "3 PCS LED Lighted Rocker Toggle Switch, 12V SPST 3 Pin 2 Position ON/Off Rocker Switch, 20A Heavy Duty Marine Toggle Switch, Illuminated Toggles Switch for Car RV Vehicles Truck Boat". The light is way too bright. I made this to dim it down, and it is perfect. Inner diameter 7mm, length 13mm.
