Abstract

A photosensitive light includes a photosensitive resistor set on the power supply circuit of the headlight, and on a predefined location (such as the control panel) of the electric vehicle. Through the installation of the photosensitive resistor, the on or off states of the headlight and the taillight can be automatically controlled with respect to the brightness of the surrounding environment. This can be applied to avoid the situations of forgetting to turn on or off the headlight due to the driver'"'"'s negligence, and can enable the lights to be automatically turned on when the electric vehicle passes shaded and dark areas to ensure the driver'"'"'s safety, and furthermore, achieves the progress of practicability of saving power, and prolonging the usage duration of the battery jar of the electric vehicle.

Claims

1. A photosensitive light for an electric vehicle comprising:

a photosensitive resistor, assembled and set at a predefined site of the electric vehicle, located on the power supply circuit of the headlight and the taillight, wherein, through the resistor, the on or off states of the headlight and the taillight can be automatically controlled with respect to the brightness of surrounding environment.

2. The photosensitive light defined in claim 1, wherein said photosensitive resistor can be assembled on the control panel lying on the head tube of the electric vehicle.

3. The photosensitive light defined in claim 2, wherein said additional control switch can be set on the control panel of the head tube, through such the vehicle can be free from the control of the photosensitive resistor, and can manually force the on or off of the headlight and the taillight.
