In replacing stock headlights on certain trucks with new Light Emitting Diode (LED) lights, the onboard diagnostic system of the trucks do not read sufficient load resistance from the new lights and so the diagnostic system indicates that there is an issue with the lighting system and consequently limits the functionality of the lighting system. The present application seeks to provide a solution to this problem by creating a headlight adapter that integrates components for imitating the load resistance and switching functions of Original Equipment Manufacturer (OEM) truck headlights (the “Headlight Adapter ”).

A combined radar and lighting unit includes a laser radar apparatus, a lighting device, and a controller. The laser radar apparatus is mounted to a vehicle, emits laser light toward an outside of the vehicle, and detects reflected light. The lighting device is mounted to the vehicle and emits visible light toward the outside of the vehicle. The controller controls the lighting device to cause the lighting device to alternately operate in a first emission mode to perform emission of the visible light, and in a second emission mode to stop emission of the visible light or reduce a quantity of the visible light. The controller controls the laser radar apparatus to interrupt the measurement of the distance while the lighting device is operating in the first emission mode, and executes the measurement of the distance while the lighting device is operating in the second emission mode.

The present invention relates to an ejectable headlight device for replacement of a lightbulb assembly from the front of a vehicle. The lightbulb assembly of the present invention has at least one lightbulb pin, a lightbulb base, a replaceable electromagnetic radiation source, an electrical connector, and a replaceable lens. The ejectable headlight device includes an ejector, a base that houses the ejector and has at least one guide for receiving the lightbulb pin. The device has a release arm that engages the lightbulb pin. The device further includes a pivot point and a pull attached to the release arm. When the release arm secures the lightbulb pin to the base, the device is in the locked position. When the pull engages the release arm to put the device in the unlocked position, the release arm pivots about the pivot point and disengages the lightbulb pin.

A vehicle lamp capsule 32 having a base 34 having a spring 5 which, when lamp capsule 32 is installed, biases an inner surface of a vehicle lamp reflector 12. Spring 5 is monolithically formed with base 34 along with at least one reflector-locating structure on the base such as circumferentially extending exterior locating surface 44 and/or retaining keys 42. Base 34 and spring 5 may be molded of a plastics material. In other embodiments base 34 and spring 5 are made in one piece of sheet metal. The spring 5 formed unitary with the lamp base 34 meets regulatory requirements and avoids a risk of dislodgement of a conventional separate piece-part metal spring which could cause an electrical short when the lamp is installed in the field. The lamp capsule 32 is suitably an H13-style lamp.

An incandescent lamp for a vehicle headlight comprising a transparent vessel that encloses at least one filament and the vessel is at least partly covered with a coating. The coating comprises at least one pigment, which is arranged such that light emitted by the at least one filament and traversing the coating is transformed to transformed light. The transformed light is characterized by a chromaticity according to the CIE 1931 xy-chromaticity with y being in between the Planckian locus and y=0.5*x+0.205 and 0.36<x<0.42, and wherein the at least one pigment comprises a mixture of CoAl oxide and CoAlCr oxide, the mixture being characterized by a ratio of a concentration in mass percentage Cm(CoAl oxide) of CoAl oxide and a concentration in mass percentage Cm(CoAlCr oxide) of CoAlCr oxide in the coating of 90/10Cm(CoAl oxide)/Cm(CoAlCr oxide)30/70.
