I love my O-Light Valkyrie because it has a white light, and a blue light. The blue light is super handy because it really makes the tritium front sight really stand out.
I'm curious, are there any other lights out there that offered a colored light, or even if there is an option for a colored filter to be slipped onto the light.
The main reason I am asking is because my O-light doesn't fit snug and I know someday it will have to be replaced.
