Rickster43,
Doesn't the X just look that much more cool with the lights? Glad to hear that I was of some help to you.
From what I can tell in the manual, you have to pull out the whole lamp assembly, twist the bulb housing on the back to open it up, release a spring clip and the bulb comes out. The bulb appears to be wired to a small plug that you uplug and then reverse the process.
I got mine aimed the other night to where I liked them and what a difference they make. My night vision seems to be getting worse as I get older and these really help to light up the road right in front of you. I was reallly impressed with them.
