nice writeup - they look awesome. you're definitely right about updating the look of the X.

turn signals are regular incandescent bulbs - two new ambers are included. I would recommend also buying some silver coated amber invisibulbs for turn signals and a pair of superwhite invisibulbs for the reverse lights at the same time. add some LED license plate bulbs and the ass of your X looks practically new.
