HID is applied to high-tech automobile purposes.  HID headlamp is a breakthrough technology to replace the conventional tungsten filament bulbs.  With Xenon filled inside a quartz tube, the 12V power is instantaneously increased to 23,000V by a precision stabilizer, activating the free Xenon electrons inside the tube, forming a perpetual super-powerful arch light perpetually between two electrodes, providing higher luminosity and a broader lighting area.  We call it “gas discharge”.  Since the super-powerful white arc light produced by Xenon is quite similar to natural sunlight, it becomes essential equipment for your traffic lighting.
