How can you burn out a filament in a HID if there is no filament to burn out. It is a tube with Xenon gas in it which glows when exposed to Hi frequency and 23,000V. That's right NO ELEMENT. This is not one of those Funky BLUE quartz bulbs. This system has a ballast which glows the gas. The system only consumes 35W and puts out about 3x the amount of light as a standard Halogen.
