I picked up my 2005 Hummer H2 on Saturday and have not had a chance to open up the rear brake light enclosure. In my Avalanche, there was enough room to wire in the original brake lights in-line and hide them behind the enclosure. (There was enough room so that they wouldn't overheat.) Since the LEDs draw almost no current, combining them with the original bulbs allowed everything to work perfectly. Just my two cents, though until I check out my H2, I cannot say if it is practical in this instance.
