I am planning to get a 90x10 cm sticker for the lower rear window and am wondering if this is legal while driving? I live in Oklahoma btw.
That's cool on YouTube I wonder how they work as far as the LED lights I have not seen something quite like that... I mean it looks like OLED but I thought that was expensive
Considering that most cars don't even have a window down there I'd say they're OK, but when you think about how it would distract the other drivers, I'd have to say the cops could make trouble for you if they felt like it.
If the lights distract following drivers, yes, illegal. Possibly on the side windows. Or in the wheels. Or the Grill. Flat on the roof.
Lets pretend you will not be playing a constant tone; in that case OK law prohibits them. (if they never flash, you are ok, but a single tone will get boring over the years) §47-12-227. Special restriction on lamps. :: 2014 Oklahoma Statutes :: US Codes and Statutes :: US Law :: Justia (if you can get your Prius defined as 'an implement of husbandry' you are good to go, except in blue)
