LOOKING AHEAD: LED VERSUS HID

LED headlights work when an electrical current passes through light-emitting diodes. There’s no filament, thus no excess heat, and LED bulbs last longer than filamentbased bulbs. LED bulbs shine brighter and further than traditional lights, and they also turn on instantly, but they can be expensive. Highintensity discharge (HID) headlights produce light using xenon gas, creating an arc of electricity between two electrodes. HID headlights are very bright, but HID bulbs can take several seconds to activate – and they’re also quite pricey.
