A method for controlling the motion of a mobile warning triangle for suitable placement on a roadway acquires information as to color of the lane markings detected by a sensor. When the mobile warning triangle is first placed on the roadway, the sensor is preset in position to detect the lane marking. White or yellow color information of the lane marking or of the black-colored roadway are detected or are not detected by the sensor, and deviations from a required path are recognized when different colors are received in certain combinations by the sensor. If no deviation is recognized in the colors, the mobile warning triangle continues moving forward. If a deviation in colors is recognized, the mobile warning triangle is controlled to hunt to the left and right through one or more predetermined angles to try to detect or redetect the lane marking.

A hazard beacon has an interface to a vehicle wiring harness configured to detect that vehicle emergency indicators have been deployed, a plurality of separately strobe capable light segments forming a hazard symbol, and a microcontroller controlling operation of the plurality of separately strobe capable light segments.

An improved light assembly includes aligned directional light sources mounted one behind another. A distal one of the light sources occludes light emitted from a proximal one of the light sources. A reflector is interposed between the light sources, with a convex surface facing the proximal one of the light sources. Thus, the light assembly projects a light field extending at least through an 180° hemisphere, and up to about 270° backwards from the forward orientation of the light field, well-illuminating lateral approaches to the assembly.

Systems and methods for deploying emergency roadside signaling devices are disclosed. In one aspect, a control system for an object placing device of an autonomous vehicle includes a processor, and a computer-readable memory in communication with the processor and having stored thereon computer-executable instructions to cause the processor to: receive a signal comprising instructions to activate the object placing device; and provide instructions to the object placing device to place a plurality of signaling devices in accordance with predetermined criteria.

A mount for inverted light has a back, two spaced apart feet beneath the back, two tabs outwardly from the back, each tab having two pieces, an arcuate shroud opposite the back and an adjustment mechanism for the tabs. Opposite the back, the feet and tabs have a low friction surface limiting engagement of the mount with door glass. The adjustment mechanism includes knobs turning rack pinion gearing and knobs ratcheting one piece of a tab outwardly from the other. Beneath the shroud, the mount has two rests that receive a light attached to them aimed downward from the shroud. The mount has an elongated form for a generally centered position along the width of a door's window.

A trim element for a tailgate of a motor vehicle. A receptacle is formed in the trim element which is open towards an inside of the vehicle and in which a warning triangle received in a case can be placed or is placed. The receptacle has: a rear wall portion having at least one elastic clamping element; two front restraining portions; a support portion; and the clamping element, the front restraining portions and the support portion are designed in such a way that they are in a form-fitting and/or force-fitting connection with the case when the warning triangle is placed. The rear wall portion has a guide portion above the clamping element which is curved concavely towards the inside of the vehicle and along which the case of the warning triangle can be introduced into or removed from the receptacle.
