A vehicle lamp control system includes an electronic control unit having a processor and a non-transitory computer readable memory including a machine-readable instruction set. The electronic control unit is communicatively coupled to a camera configured to output image data of a vehicle environment, a vehicle lamp and a steering wheel sensor. The machine-readable instruction set causes the processor to receive the image data of the vehicle environment from the camera, determine whether an external light source is present in the vehicle environment based on the image data of the vehicle environment, determine a steering wheel angle based on an output signal of the steering wheel sensor, and generate a control signal for activating the vehicle lamp when the steering wheel angle exceeds an activation steering threshold and no external light source is detected in the vehicle environment.

A light source module includes first LED elements that emit blue light, second LED elements that emit amber light, and a wavelength conversion member disposed in optical paths of the first LED elements and the second LED elements. The wavelength conversion member converts a portion of the blue light emitted by the first LED elements to yellow light, transmits a portion of the blue light emitted by the first LED elements, and substantially transmits the amber light emitted by the second LED elements.

A light reflective cover includes a concave main reflective surface and a ridge having a connecting surface, a ridge-top reflective surface, a light source end, and a light emitting end. The light source end and the light emitting end are opposite to each other. The connecting surface is opposite to the ridge-top reflective surface and connected to the main reflective surface. The ridge-top reflective surface extends between the light source end and the light emitting end. The ridge-top reflective surface includes a step for dividing the ridge-top reflective surface into a first part near the light source end and a second part near the light emitting end. The second part recesses with respect to the first part toward the connecting surface. The endpoint of the second part at the light emitting end does not protrude beyond an extension line along a first arc formed by the first part.

The invention provides a vehicle lamp which includes a lens, a lighting module, and a mask. The lens includes an optical axis. The lighting module includes a first LED lighting source which includes a first substrate to dispose a plurality of LEDs on the first substrate and includes a first lighting projection direction parallel to the optical axis for emitting a first light beam through the lens to a projection plane. The mask is located between the lens and the first lighting source, and includes an edge for partially shading the first light beam to form a cutting line between a light area and a dark area on the projection plane. The first LED lighting source is adjacent to the mask in a distance less than 5 mm.
