Casio Pro Trek PRW-30 Mod series Part 2

In this vid I have removed the mirror backing to allow more light in to better charge the lume. While it worked and lume would now glow as you exit room into dark, it made normal viz pretty bad. Not happy with it so will be changing again so part 3 coming soon.
