Since LEDs draw less electrical current than the halogen bulbs that you've replaced -- the car sends a series of signal to check to see if anything is there thus resulting in the flashes.

Although it reduces a bit of weight, I'm not willing to compromise on what our cars already lack just for a little bit of noise. Although I would definitely consider getting this whole system one day given he doesn't sell it
