No, you are not. After using black electrician's tape, Gorilla Duct Tape, and about everything else, I found the blue painter's tape to be the best. However, I still have enough light seeping through to make a glowing rim around my windshield that is kind of annoying, but also kind of cool. I am experimenting with making some kind of a permanent visor for the headlight. Think it would take the retro look one step further.
