Agron, I put a post about the installation somewhere but.... its real easy. First you pop the plastic rear housing that holds the bulbs (as if your changing a bulb) then there are 5-6 nuts that need to be removed, they hold the lens in place. You then have to push the lens from the inside outwards. It should pop out.
Note: for every nut there is a second nut next to it. Do not loosen the second nut its for the actual bolt embedded in the lens. I almost did

.
Hope this helps.
