Various examples are provided related to boat loaders for trailers. In one example, a boat loader includes a primary tube extending between a first end and a second end and a light tube that can move within the primary tube. The light tube can include light elements extending along a portion of the light tube at a first end and a float attached to the light tube at a second end. The primary tube can be coupled to a trailer at the second end and the first end of the light tube can extend outward from the first end of the primary tube exposing the light elements as the primary tube is submerged in water and can retract into the primary tube as the primary tube is removed from the water.

This light-emitting element drive control device (100) comprises: a drive logic unit (113) which performs a drive control of a switch output stage (N1, D1, L1) for dropping an input voltage (VIN) to an output voltage (VOUT) and supplying a light-emitting element therewith; a charge-pump power supply unit (a) which generates a step-up voltage (CP) higher than the input voltage (VIN); and a current detecting comparator (114) which receives a supply of the step-up voltage (CP) and the output voltage (VOUT) as power supply voltages, and generates control signals (SET, RST) for the drive logic unit (113) by directly comparing a current detection signal (Vsns) corresponding to an inductor current (IL) of the switch output stage with a peak detection value (Vsns_pk) and a bottom detection value (Vsns_bt).

A vehicle warning lamp is provided, including: a base, including a receiving room, the receiving room extending in an axial direction; a light-emitting module, disposed within the receiving room, the light-emitting module including at least one light-emitting member; and a light guide, including a first side and a second side opposite to each other, the second side facing toward the light-emitting module, the first side including a first diffuser, the light-emitting module being located within an axial projection area of the first diffuser, the second side including at least one inclined portion and at least one plane portion, the at least one plane portion being perpendicular to the axial direction, each of the at least one inclined portion including a second diffuser which is located outside the axial projection area of the first diffuser.

A lighted applique for a vehicle body panel including an opaque body panel applique and one or more display element cutouts each having a cutout profile formed in the opaque body panel applique. At least one non-opaque display element is mounted within the one or more display element cutouts such that a panel engagement surface is in contact with a panel exterior surface. At least one LED strip is mounted within the at least one LED strip channel and an electrical connection assembly is in communication with the at least one LED strip.

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.

A system includes at least one light pipe, at least one light source disposed at least partially within an interior of the system, a lens substantially enclosing the interior, the at least one light pipe, and the at least one light source, the lens having a continuous transparent or translucent coating on the outer surface, with the at least one light source receiving electrical power from the electrical power source, the continuous transparent or translucent coating being at least partially permeable to at least some light which is emitted by the at least one light source and passed through the lens, and at least one mask located between the at least one light pipe and the lens, a plurality of small contact areas being provided on the outside or inside of the light pipe or on the mask.

Design of identification and visual protection system for mining equipment, vehicles and people exposed to possible high potential interactions, this system is the combination of different lighting techniques, which together offer a new product with the advantages of delivering a Greater capacity to be visualized in the field, preventing identification and warning problems in mining equipment.

Its form and use can help reduce the risks and exposure of equipment, vehicles and people where they can be implemented. Considerably increasing the identification distance, even without any external light emission.

An apparatus (100), including: a framework (104) configured to be secured to a vehicle; an arm base (106) configured to pivot relative to the framework between a retracted position and an extended position; an arm (110) removably secured to and extending from the arm base; and a shock absorber (142) configured to absorb shock and to prevent relative movement between the arm base and the arm.

Disclosed are an organic light emitting display device and lighting apparatus for vehicles using the same. The organic light emitting display device includes a first layer including a first organic layer and a first emission layer on a first electrode, a second layer including a second emission layer and a second organic layer on the first layer, a second electrode on the second layer, and a third organic layer between the first layer and the second layer. A thickness of the first emission layer is equal to or greater than a thickness of each of the first organic layer and the second organic layer.

A reflector unit may behave as a retroreflector to reflect light of a selected color. The reflector unit may comprise a first reflector having a first color, a second reflector having a second color, and a mask that either allows incoming light to reach the first reflector and not the second reflector or allows incoming light to reach the second reflector and not the first reflector. An active light unit may emit light of a particular color in response to receiving light. In this fashion, the active light unit may simulate the operation of a reflector. The reflector unit and the active light unit may operate on a bi-directional vehicle.
