I am a Malibu dealer and can sell you lights from Metcraft, the people who make the tower. There are two different types available right now. The bullets are stainless steel and the dome are polished chromed aluminum
If you want the slickest looking lights I would go with the lights from Westwinds. You can get them from dealers. See them at www.westwindsonline.com. Drop me a message at info@bakesonline.com if you have any specific questions about them.
