Ah, glad to see that the sticker can fit sitting down on the window strip. That's where mine will go, and I didn't want it an inch above the strip like the others have been
I think since I only am getting one atm, I will put it in the lower right corner of the rear windscreen, the other side has my K&N sticker.
IMO, red might look out of place. White is the best to be able to see. Black near invisible and red might blend too much from a normal driving distance. Just my opinion though.
