Halos ( rings of light surrounding the outside edge of the reflectors on vehicle headlights) were originally developed by BMW and now aftermarket manufacturers are offering halo kits for many different makes and models. I found this halo kit for the Jeep Commander on ebay, marketed by a company called Advanced Automotive Concepts. This halo kit uses CCFL (cold cathode fluorescent lighting) core technology. CCFL produces a very white light with a very slight hint of blue or cyan. The look is very "high tech" and matches HID equipped lights exceedingly well. Additionally, this technology provides for very bright output from the halo rings so they're visible day or night. It can be installed in under four hours if you are moderately experienced.
