Added LED front signal lights to compliment the rear LED signals. Love the way they look, and so does the wife. She demanded I immediately order her some for her X5.
The ones I used can be ordered from SiriusLED on Amazon. The rears I can't link to as they were purchased years ago for our first Optima SX, then used on our second Optima SX, and now on the X5. Fronts:

They are switchbacks, but the white portion of the LED does not get utilized on the X5 as our front sockets only utilize 2 contacts and the LCM does the switching between parking and signal +12v (I'm guessing anyway). Just as well. With as bright as the LED rings are for the halos, I don't think it would look very good having the parking lights be white.
Here are a couple of vids:
