DETAILED DESCRIPTION

[0021] As discussed above, embodiments of the present disclosure relate to vehicle safety accessories and more particularly to a dynamic brake light system as used to improve the vehicle brake light art.

[0022] Generally, a dynamic brake light system may generally comprise a customized brake system comprising a vehicular deceleration detector and an elongated brake light to help improve safety on the roadways. The elongated brake light may advantageously include sequential illumination based on a measurement of the vehicle's deceleration. The light array on the brake light may include one or more colors and may increase in strength or length from the center and outward depending on the measurement of the vehicle's deceleration.

[0023] In such a manner, a motorist may apply a light amount of pressure to illuminate the center portion of the elongated brake light. As more pressure is applied, the LED light extends on both sides of the brake light system. If pressure is fully applied to the brake to stop the vehicle, the LEDs illuminate the entire elongated brake light, and may even pulsate if the measurement exceeds a maximum deceleration reading. Other motorists on the roadway may then be able to identify how much pressure is being applied to the brake depending on how much of the elongated brake light is illuminated.

[0024] A computational system may also be equipped within the brake system designed to decipher the pressure/speed ratio to determine how much the light should be illuminated. This may particularly be useful in stop-and-go situations in traffic where drivers may apply light pressure to the brake, but not further illuminate the brake light. The system may be configured to illuminate the light in a manner to extend the full length of the bar, signifying a full stop.

[0025] The dynamic brake light system may be constructed using plastic and other suitable materials. The system may be connected directly to a vehicle's interior wiring, thereby accommodating virtually any make or model of vehicle. The system may be manufactured directly into a vehicle or installed as an after-market accessory.
