====Cold lenses==== Before LEDs, all light sources used in headlamps (tungsten, halogen, HID) emitted [[infrared]] energy that can thaw built-up snow and ice off a headlamp lens and prevent further accumulation; LEDs do not. Some LED headlamps move heat from the heat sink on the back of the LEDs to the inner face of the front lens to warm it up,{{Citation needed|date=May 2018}} while on others no provision is made for lens thawing.
