A lighting apparatus of an autonomous vehicle may include: a roof formed at the top of a vehicle; a lighting unit installed on the roof, and configured to display an autonomous driving status of the vehicle to the outside; and a control unit configured to vary a lighting status of the lighting unit according to the autonomous driving status of the vehicle.

A vehicular apparatus includes: a housing that is configured to be attached to a vehicle; and a first light source and a second light source that are provided in the housing to emit light having main wavelengths in mutually different wavelength ranges. The first light source emits light having a main wavelength in 490 nm-498 nm while the vehicle is being automatically driven.

A method for controlling and switching operational modes of an additional lamp for a vehicle includes confirming a pre-set operating mode of the additional lamp. The additional lamp is switched from the pre-set operating mode to another operating mode only when a continuous first signal and intermittent plural second signals come from the vehicle. When the brake is operating and the additional lamp is in a non-flickering mode, the additional lamp generates non-flickering light. When the brake is operating and the additional lamp is in the flickering mode, the additional lamp generates flickering light. The additional lamp is turned off when the braking operation stops. When the braking operation continues and the additional lamp is in the flickering mode, the additional lamp keeps outputting flickering light. When the braking operation continues and the additional lamp is in the non-flickering mode, the additional lamp keeps outputting non-flickering light.

An illuminated door sill plate contains: a base and a removable cover. The base includes an elongated case, a waterproof plate, a PCB having a light-emitting diode (LED), a light guide plate, and at least one changeable battery. The elongated case has a light emitting portion, multiple engagement portions, at least one first receiving orifice, and at least one battery cover. The removable cover includes an elongated body connected with a nameplate, and the nameplate has a light transmission portion formed on center of the nameplate in multiple character shapes and configured to transmit lights, an elongated groove formed on center of a top of the elongated body, and multiple hooks extending from two long sides of the elongated groove and engaged with the multiple engagement portions so that the base is connected with or removed from the removable cover.

A vehicle rooftop beacon for drawing attention to a vehicle from afar. The rooftop beacon includes a base, and a light beacon elevatable above the base by an extendable mast. The base also has at least three support feet to stabilize the rooftop beacon when placed upon a vehicle rooftop. The light beacon is thereby supported high above the vehicle rooftop so that the vehicle is more visible to emergency response vehicles from far away. The base can also include a plurality of side-mounted or edge-mounted lights to further call attention to the vehicle. The rooftop beacon is convenient, portable, and lightweight. The support feet can include magnets or weights to stabilize the rooftop beacon on the vehicle rooftop in windy or stormy conditions. The support feet also can include a soft foot covering, such as rubber, to prevent scratching and slipping off of the surface of the vehicle rooftop.

Disclosed is a directional warning light designed to bend along its longitudinal axis up to about 30° so as to conform to curved vehicle surfaces. Flexible components of the disclosed embodiments allow the bending and include a bendable optic, bendable base, and bendable circuit substrate.

Systems and methods to activate one or more indicators, positioned on heavy hydraulic-based equipment to provide indication that the heavy hydraulic-based equipment is in an operation are described herein. The system may include a hydraulic initiation lever positioned proximate an operator's seat of the equipment and configured to be actuatable to an inactive position and an active position, the hydraulic initiation lever when in the active position configured to generate an unlock signal to thereby enable hydraulic operation of the heavy hydraulic-based equipment. The system may include one or more indicators configured to receive the unlock signal, the one or more indicators configured to activate in response to reception of the unlock signal and to deactivate in response to no reception of the unlock signal.

Some examples of an active-alerting apparatus (AAA) are disclosed. The AAA is configured to be associated with a standing vehicle. Some embodiments of the AAA can have a structure of a flag (AAF) other embodiments of AAA can have a structure of a triangle (AAT) other can have a structure of a folding triangle (FAAT). Examples of AAA can be associated to a window of the standing vehicle or to an adaptor for holding the AAA. The adaptor can be a pip that is associated with the back of the wagon and is configured to hold the AAA such that the AAA faces the coming traffic. The AAA can be associates with retro-reflecting red area, red-fluorescent area and one or more light sources, such as LEDs.

A lighting element includes a circuit board defining a longitudinal axis and including at least one illuminator thereon, a housing having at least one flexible element in the optical pathway of the at least one illuminator and in register with the at least one illuminator on the circuit board, and with opposing axial ends.
