An auxiliary lighting system for a helmet operable with a lighting system of a vehicle comprising a vehicle brake light, comprised of a helmet portion and a vehicle portion. The helmet portion is comprised of a helmet lighting unit, a microcontroller in communication with the helmet brake light, and a helmet transceiver in communication with the microcontroller. The vehicle portion is comprised of a supporting body, a vehicle transceiver, and an accelerometer joined to the supporting body and in communication with the microcontroller. The microcontroller is programmed with an algorithm such that the microcontroller receives a signal indicative of the relative position of the accelerometer, determines the performance capability of the accelerometer in detecting acceleration of the vehicle with respect to the Earth based upon the signal indicative of the position of the accelerometer, and presents an indication of accelerometer performance capability.

The invention relates to a protective sports helmet purposely designed for a selected group of helmet wearers from amongst a larger population of helmet wearers. A multi-step method for helmet design starts by collecting information from a population of players that may include information about the shape of a player's head and the impacts the player has sustained. This information is then processed to create player population information that is sorted to create categories. Advanced mathematical techniques are utilized to further sort these categories into player groups or data sets based on player attributes. Once the player groups are identified, another multi-step process is utilized to design optimized helmet prototype models for each player group. These optimized helmet prototype models are then further processed into complete helmet models by determining a structural design and chemical composition that is manufacturable and has mechanical properties that are substantially similar to the optimized helmet prototype model. Physical helmet prototypes are then created and tested using a unique helmet standard derived from information associated with each player group. Once the prototypes pass testing, the complete helmet models can be manufactured to create actual stock helmets or stock helmet components for future players whose characteristics and attributes place them within the selected player group.
