A vehicle lamp uses a light conversion member to transform blue excitation light into red emission.

A vehicle signaling light uses asymmetrically expanded portions in a light guide plate to distribute LED light evenly across the output surface.

A lighted guide post assembly uses angled support posts and translucent circular tubes to suspend LED strips for continuous illumination.

Direct wiring from rotary connector to vehicle body removes substrate paths and protective components, reducing steering module manufacturing cost.

An illumination controller adjusts light pattern length based on vehicle intervals to resolve visual communication gaps during autonomous lane changes.

Microprism structures in the light guide plate redirect LED light through the transparent shell, resolving low luminance and assembly complexity issues.

A rearview device bezel houses light assemblies and electronic modules within a sealed structure to consolidate multiple vehicle functions.

Overlapping stepped portions in segmented light guide elements mix light to resolve uneven illumination at sharp angles while reducing manufacturing volume.

A light projector mounts on a chute guide link to illuminate the snow dropped position during operation.

A dynamic threshold adjustment mechanism reduces time lag and false detections by varying measurement counts according to proximity.
