You can add a resistor to stop the hyper flashing.bought these back in Aug 2017 on Amazon for my 17 hatch and still working fine...back then the cost was I believe around $36.99, but now it's like down to $26.99.

highly recommended...you can only put on the front or the back sides (one or the other, otherwise you'll have hyperflashing).
Normal is a blob of light. LEDs create specific bright shapes. https://www.google.com/search?q=maz...gK0KHcCtDSEQ_AUIDigB&biw=1920&bih=976#imgrc=_how can you tell the difference between a led or normal tail light?
Easy. Don't buy cheap generic crap. If it isn't labeled as LED assume it isn't LED. Move on and find proper LEDs somewhere else...:surprise:Yeah but how am I shure that it is an LED when i'm buying it from a store because it doesn't say it anywhere?
