You'll be fine, but you WILL have fast blinker. You'll need a resistor pack. I've used them in the E28 (sold), E34 (sold), E39 and now the E88 with no issues.
Just as a heads up, I have an 18 SMD (1.6 watts) surface mount LED) version coming very shortly. It's brighter than the standard mini LEDs most are using. More isn't always better
