Disclosed is a system for providing vehicle indicator lights, such as brake lights for a bicycle or motorcycle. The system may include at least one indicator light, a gyroscopic sensor, an accelerometer, a power supply, and a signal processing unit that receives inputs from the gyroscopic sensor and the accelerometer and activates an indicator light based on inputs from the sensors. Various algorithmic functions and other features may also be included in the system to make detection more robust and the make the system useable for a variety of different vehicle applications.

A system for implementing strobing of existing vehicle hazard lights including an interface to a vehicle wiring harness configured to receive input to an existing vehicle flasher module, and a strobing circuit that responds to an activation signal from the vehicle wiring harness that is indicative of a hazard flasher deployment event by producing an electrical output through the interface to the vehicle wiring harness that causes a strobing of existing vehicle hazard lamps.

Disclosed are a method and a system for controlling a lamp in a bicycled device. The method includes: detecting an acceleration value of the bicycled device; and controlling a brake lamp of the bicycled device to be switched on and off, according to the acceleration value of the bicycled device. With the technical solution according to the embodiment of the invention, the brake lamp of the bicycled device can be controlled automatically by detecting the acceleration value of the bicycled device to thereby improve the safety of the bicycling bicycler, better satisfy the user, and improve the experience of the user.

A vehicle license plate holder having a frame including a receptacle for a license plate, first and second LED light sources disposed on each side of the frame, and one or more power generators attached to the frame. The frame also mounts an electronic circuit module including a battery and configured to detect deceleration of a vehicle and to illuminate the first and second LED light sources in response to detection of the deceleration.

A system for implementing strobing of existing vehicle hazard lights including an interface to a vehicle wiring harness configured to receive input to an existing vehicle flasher module, and a strobing circuit that responds to an activation signal from the vehicle wiring harness that is indicative of a hazard flasher deployment event by producing an electrical output through the interface to the vehicle wiring harness that causes a strobing of existing vehicle hazard lamps.
