Is it clear enough to distinguish a green arrow from an actual green?

I'm one of those fools that tends to goose it every chance I get and the last thing I wanna do it gun it on a green turn arrow

Sunlight is not really a problem - it gives you a small, somewhat distorted view of the signal and once you have the signal picked up seeing it change from red to green is obvious (provided you have the right signal )

You can distinguish the green arrow, but you're looking at a much smaller image in the prism than you see looking at it directly.

I don't pull into an active intersection without first glancing at the actual light (after seeing it change in the prism) or seeing that adjacent cars are moving away from the light, too. With a prism you may be picking up other light sources that catch your eye, too, especially at night, and goosing it away from a red light is a good way to get broadsided, even if you have the green light. Trusting the prism alone would be like driving with a periscope - you may be able to do it, but why add to the risks that are already there?? Maybe adapt a rear view video camera/mirror display?? (Just kidding, just kidding.....)
