Examples of the present disclosure relate to techniques for headlamp heater control. In examples, a headlight assembly comprises a heater, which is used to prevent or remove condensation/precipitation on a lens of the headlamp assembly. Given it may be difficult for an individual to know when to manually turn the headlamp heater on, an electronic control unit (ECU) may evaluate a set of rules to determine when to automatically enable or disable the headlamp heater. The rules may be associated with atmospheric conditions outside the vehicle, the state of the vehicle (e.g., whether windshield wipers are turned on, whether windshield defog is enabled, whether a mirror heater is turned on, etc.), and/or user input received by an ECU of the vehicle, among other examples.

Headlamp reflector

Examples of the present disclosure relate to a headlamp heater for a headlamp assembly. In examples, a headlamp assembly comprises a heating element, which directs radiation toward a lens of the headlamp assembly in order to prevent or remove condensation/precipitation on the lens. In examples, the heating element is an infrared heating element, and the wavelength of radiation emitted by the heating element is selected to be a wavelength that excites water. In some examples, the heating element is angled toward the lens and/or has multiple angled surfaces, thereby altering the radiation pattern that is directed toward the lens such that it better matches the beam pattern of a light source in the headlamp assembly.

Headlamp heater

Optical features of a light bulb, a bezel, an amber lens, and a cover lens of a headlamp assembly combine such that the headlamp assembly can meet all requirements for forward-facing turn signal, side-facing turn signal, side marker light, and side reflex refractor functionality with a single light bulb including two filaments.
