@Corallus - Kessil warns against attaching anything to the lamps in the case they interfere with airflow or cooling, so take that as caution. There's about 1"+ of space between the Kessil lense and the edge of the lens cover assembly. These are 1/2" x 3" 3-led strips, so I used a 3M adhesive strip to mount them on the lens cap surface. It's not the most beautiful setup, but it works and has not interfered with cooling or airflow. I wound the cables for these around the goosenecks with the Kessil power lines.
