Abstract: Methods and systems for vehicle safety lighting are disclosed, including a system having a multi-axis accelerometer that detects acceleration of the vehicle along a first axis and a second axis normal to the first axis, and outputs a corresponding first axis acceleration measurement and a second axis acceleration measurement. A controller is coupled to the multi-axis accelerometer, and to an array of light emitter elements (LELs). The controller is configured to determine a vehicle deceleration, based at least in part on a combination of the first axis acceleration measurement and second axis acceleration measurement, and to detect the vehicle deceleration exceeding a brake light threshold and, based at least in part on the detection, output a deceleration light signal to the array of LELs.
