Look for attachment on page and also attached to this tutorial if link dies

If you replace the turn signal and marker light (side bulbs) with LEDS they then flash really fast because of difference in current required and the way the turn signal relay works. There are no replacement relays available since the BMW relay is unique vs may other cars.
This modifies the stock BMW relay to work with lower current using a diode vs the resistor that works with stock bulbs that are much higher current.

The Diode just needs to be similar specs.. i used

Hope that helps someone else.. definitely makes LEDS work better. i have personally put this in and it works!!
