Come on, it's a lens cap. Even people like me can replace a lens cap. But it's not just any old lens cap, it's a Chris Products Turn Signal Red Lens with Blue Dot. Ok another story from Not Mr. Fix It, but a true one. I pulled into the Dillons store the other day (not night) and a Blue Hair yelled youhu (you hoo) at me. I stopped to see what she wanted and she complimented me on my back lights on my motor bike (as she called it). She said normally she can't see the brakes light up on cars or bikes, and always has to slam on hers, but she said she had no problem seeing the blue dot in the middle of my lens. No, she doesn't get a free motorbike ride, but if you see a tag that say's BlindAsBat, just turn the corner and take another street before the Blue Hair has another near miss!
