Safety Tail Light

Vehicle Safety Taillight

Vehicle Safety Taillight designed along the concept developed by SureLight bike light that shows others when you slow down and when they get too close.  Styling Design along the same lines as aftermarket vehicle rear lights sold by Hammacher Schlemmer.

Feature Content:

1. Attracts motorists’ attention as it varies the brightness, color, and flashing pattern of the light in response to vehicle deceleration and proximity to others.
2. Proprietary algorithms process data from its built-in accelerometer and proximity sensor, activating the red light and flashing orange hazard lights when a vehicle behind gets too close. Incorporates two sensors – a LIS3DH acceleration sensor and a VL53L1X proximity sensor; a controller; a battery; a set of RGB LEDs.

3. Housed in an aluminum casing with a polycarbonate front filter with 3-year life cycle battery life.
4. The controller is set up to initiate three emitting modes, which may be active together or separately.
5. A first mode (ultra-bright red LEDs are on), active unless another mode is initiated.
6. A second mode (ultra-bright red LEDs are made brighter, i.e., brake lights), initiated when a pre-determined acceleration/deceleration range is met.
7. A third mode (ultra-bright orange LEDs flash, i.e., hazard lights), when a predetermined proximity range is met, e.g., when an object is detected close to the vehicle.
8. The controller can adapt the acceleration range or proximity range with regards to each other. For example, if the acceleration is detected above a higher pre-determined threshold then the proximity range may be increased, i.e., the vehicle is decelerating very rapidly, and the third mode is initiated when a vehicle is further away than usual.
9. The controller also includes a digital signal processor, which processes signal data from the sensors in real-time so that a single anomalous measurement (e.g., hitting a small pothole, some dirt falling past the light, etc.) does not automatically initiate a change of mode.
10. With an additional built-in reed switch, the magnets deliver an automated power-on/power-off function.

SureLight (Reference https://surelighttech.com/)  is bike light that shows others when you slow down and when they get too close. It resembles a car’s brake and hazard lights – red and orange signals understood by everyone on the roads. SureLight is safe, smart, bright.

• Safe. Attracts motorists’ attention as it varies the brightness, color, and flashing pattern of the light in response to cyclists’ deceleration and proximity to others. Patent-pending technology is based on the US Transportation Research Board’s guidelines.
• Smart: Proprietary algorithms process data from its built-in accelerometer and proximity sensor, activating the red light when it’s magnetically attached to a bike, brighter red brake lights when a bicycle decelerates and flashing orange hazard lights when a vehicle behind gets too close.
• Bright: Incorporates ultra-bright red and orange LEDs so cyclists are visible on the roads all the time, everywhere.

In the UK and US combined, a cyclist gets killed every day (on average) when hit from behind. SureLight is designed to solve this problem, making a cyclist more visible on the road by reacting to both a cyclist’s intrinsic conditions (deceleration) and extrinsic conditions (other vehicles’ proximity).

 Basic Application Design:

1. Incorporates two sensors – a LIS3DH acceleration sensor and a VL53L1X proximity sensor; a controller; a battery; a set of red and orange LEDs.
2. Housed in an aluminum casing with a polycarbonate front filter. The battery is rechargeable via a standard micro-USB cable.
3. The controller is set up to initiate three emitting modes, which may be active together or separately.
4. A first mode (ultra-bright red LEDs are on), active unless another mode is initiated.
5. A second mode (ultra-bright red LEDs are made brighter, i.e. brake lights), initiated when a pre-determined acceleration/deceleration range is met.
6. A third mode (ultra-bright orange LEDs flash, i.e. hazard lights), when a predetermined proximity range is met, e.g. when an object is detected close to the bicycle light.

The controller can adapt the acceleration range or proximity range with regards to each other. For example, if the acceleration is detected above a higher pre-determined threshold then the proximity range may be increased, i.e. the bicycle is decelerating very rapidly, and the third mode is initiated when a vehicle is further away than usual.

The controller also includes a digital signal processor, which processes signal data from the sensors in real-time so that a single anomalous measurement (e.g. hitting a small pothole, some dirt falling past the light, etc.) does not automatically initiate a change of mode.

With an additional built-in reed switch, the magnets deliver an automated power-on/power-off function.
