Looks cool, but more would be better, like a yellow or white shadow. Also, what is the meaning? Splash, RAV4, Speed. Define it. A little word like, RAV4, Turbo, Cool your name. Some thing that people can read and understand what is your purpose for putting it their.
Example; Some guys put bullet wholes! Meaning "Watchout, I got a gun!"
I like it when you see a 5Liter Mustang(or any car) with "No Fear" stickers on top of the windshield or on the side windows. And see a Police car beside it at a red light with "Fear This" sticker on the Police car.
