Abstract: An adjustable vehicle light device for a vehicle includes a housing secured to the vehicle, a reflector disposed in front of the housing, a light bulb slidably engaged through the bore of the reflector. A solenoid device is received in the housing and coupled to the light bulb for moving the light bulb relative to the reflector and the housing and for adjusting the light beam of the vehicle. The solenoid device includes a core slidably received in a coil and coupled to a socket of the light bulb for moving the socket and the light relative to the housing and the reflector.

Abstract: A light-emitting structure is intended to be mounted on the exhaust tailpipe of a motor vehicle and formed of a tubular connector, an electronic control board, and a light shield. The tubular connector is fastened at the inner end to the exhaust tailpipe and provided with a fume channel via which exhaust fume is discharged into atmospheric air. The control board is fastened to the outer end of the tubular connector such that the control board is separated from the fume channel by a heat-insulating material. The light shield is provided with a plurality of grooves and is fastened to the outer end of the tubular connector, so as to shield the control board. The control board comprises an integrated circuit and a plurality of light-emitting bodies which are corresponding in location to the grooves of the light shield.

Abstract: A warning light device for attaching onto various objects includes a housing having a base plate which has a forwardly and inwardly extended outer peripheral flange, for forming a chamber in the base plate. A cover includes a rearwardly extended outer peripheral flange engaged onto and secured to the outer peripheral flange of the base plate by welding processes. A circuit board is received in the base plate, and a number of light devices are attached to the circuit board for generating warning lights. A metal plate may maintain the housing in a suitable curvature.

Abstract: A light includes a casing for securing to an object, such as the head light housing, a socket slidably received in the casing for supporting a light bulb, and a reflector disposed around the light bulb. The light bulb is a high intensity light bulb that may generate a strong light. A cable is coupled between the socket and a solenoid device, for moving the light bulb relative to the reflector to adjust a light beam of the light device when the solenoid device is energized. A spring may be engaged with the cable for recovering the light bulb relative to the reflector.

A solenoid device is received in the housing and coupled to the light bulb for moving the light bulb relative to the reflector and the housing and for adjusting the light beam of the vehicle. The solenoid device includes a core slidably received in a coil and coupled to a socket of the light bulb for moving the socket and the light relative to the housing and the reflector.

Abstract: A two-piece clip including an elastically adjustable ferrule and a clip member detachably connected to the ferrule is provided. The ferrule is formed from a long strip of metal material with suitable elasticity and rigidity and having a predetermined inner diameter. Two free end portions of the strip forming the ferrule are caused to cross each other to form a handle portion outside the ferrule. By applying a compressive force on the handle portion to push the two free end portions inward relative to each other, the inner diameter of the ferrule is elastically enlarged for easily putting the ferrule around a pen. The outermost ends of the two free end portions are curved to form two small hollow cylinders, into which the clip member is detachably inserted and thereby connected to the ferrule. The clip member has a small length upward projected from the ferrule for connecting one or more ornamental or advertising article thereto.

Abstract: The invention relates to an automatic optical fiber stripping machine and, more particularly, to an automatic optical fiber stripping machine, which is practical for stripping optical fibers of different diameters efficiently. The automatic optical fiber stripping machine helps the user obtain the desired length of bared glass core for further standardized coupler, optical passive component manufacturing, and accurately strips optical fibers of different diameters without damaging the glass core.

Abstract: A clamping pen composed of a clamping tube receiving a core rod member and a clip member extending outward from the clamping tube. The clamping tube has an upper open end and a lower end. The upper end is formed with multiple annular projections and two lateral axially extending slots or fissures. A flange is formed on the clamping tube below the clip member, serving as a fulcrum, whereby when the clip member is pressed down or released, the fissures are expanded or contracted, permitting the rod member received in the clamping tube to be easily moved outward or inward to adjust a protruding length of the rod member. After the adjustment is completed, the clip member is released and the annular projections of the clamping tube are tightly held to contract the fissures and tightly clamp the rod member for easy use.
