LED turn signal

I have a 2018 Santa Fe Sport Ultimate 2.0T I just purchased but want to change turn signal bulbs to LED bulbs. For some reason they aren't to begin with. Problem is when I changed them I get the "Hyper Flash" which is they blink rapidly. I read I can change flasher relay but is that something I should get through Hyundai or is a local Auto supply ok?

Thanks in advance

Aint happening...

Flash control is an internal logic function of the Smart Junction Box (I/P fuse box) for left and right side (2 seperate logic control)

You will need to install some sort of load device to fool logic into thinking we using power hungry light bulbs,, that why we have fast flash when we lose a light bulb, circuit consume less current with missing bulb filament
