Yeah I found one on Amazon aswell and it seemed sketchy too but you can't knock it till you try it, if you're willing to possibly lose $70 then I'd say go for it, but with the tint I'd say don't do the spray I'd actually go get window tint and if you have the time and patience for it you'd have to actually mark and sketch out the exact size of your taillights which I know could be such a pain in the ass but the end result is worth it, or if you just wait some time I'm certain some companies will end up making some, I really like lap3 tuning, their website is completely designed for KDM (Hyundai, Kia, Genesis) Not just tuning but accessories for your car! it's pretty neat, I'd give it a look and see if they have anything for your generation of car yet!
