Abstract: A bidirectional lighting device for a rim includes a casing, a light-emitting module, a reflecting element, and a power supply unit. The casing includes a lower base and an upper cover both provided with a transparent region respectively. The light-emitting module is received in the casing and has light-emitting diodes arranged in a strip. The reflecting element is mounted in the casing to correspond to the transparent regions. The reflecting element has a first reflecting surface and a second reflecting surface both located on one side of the light-emitting diodes. The light generated by the light-emitting diodes is reflected by the first and second reflecting surfaces to exit the transparent regions. The power supply unit is received in the casing to be electrically connected with the light-emitting module. Thus, the light of the light-emitting diodes can be emitted out of the casing in two directions.

Abstract: An automobile wheel rim light decoration device includes a light emitting module, an adjustable rod and a pair of sensing elements. The light emitting module includes a retaining base disposed at the wheel rim and a light emitting unit fixed to the retaining base. The adjustable rod includes a fixed rod installed at the retaining base and a movable rod coupled to the fixed rod. The sensing element includes a first sensing elements fixed to an automobile brake component and a second sensing element corresponding to the first sensing element and fixed to the movable rod for detecting signals of the first sensing element. The fixed rod is moved horizontally in a through slot of the retaining base, and the movable rod is moved vertically with respect to the fixed rod, such that relative positions of the first and second sensing elements can be changed to achieve the desired sensitivity.
