The present invention provides a rear-end collision system and methods. A rear-end collision avoidance system includes: a signaling device made of: a geometric-shaped main body having inner LED light panel connected to the brake pedal of the vehicle, wherein the inner LED light panel is configured to display at least one sign when brake is applied, an array of light emitters disposed along a periphery of the geometric shaped main body to emit lights associated with the at least one sign, a laser unit disposed at the bottom of the geometric shaped main body, wherein the laser unit is configured to project laser line on the road relative to ending of the load to notify the following vehicle to maintain a safe distance from the laser line in order to avoid collision, and at least one connector that is configured to secure the main body onto load of the rear portion of a vehicle.

In some embodiments, an apparatus, comprises an unmanned vehicle configured to be disposed with a vehicle and a processor operatively coupled to the unmanned vehicle. The processor is configured to receive a first signal indicating a stop of the vehicle without a user request and a second signal indicating a location of the vehicle. The processor is configured to determine, based on the location of the vehicle, a target location in a pre-defined area surrounding the vehicle. The processor is configured to send a third signal to the unmanned vehicle to instruct the unmanned vehicle to move to the target location to alert other vehicles via a warning regarding occurrence of the stop.

Provided are a towing accessory for vehicles and method of operating them. The accessory comprises a mounting frame; suction cups, mounted to the frame in a spaced-apart arrangement; and a ferromagnetic attachment member attached to the frame at a side opposite the suction cups. Magnetic tow light system may thus attach to vehicles surfaces that are not magnetic via the accessory. The accessory has rotatable adjustments to enable the lights to face the required direction and mount to contours of the vehicle.
