A headlight device includes a light source, a base member, a light distribution formation member, a rotary member, a projection lens and a transmission mechanism. The base member holds the light source. The light distribution formation member forms a light distribution pattern. The rotary member holds the light distribution formation member and is held by the base member to be rotatable. The projection lens is held by the rotary member to be rotatable around a rotation axis orthogonal to a rotation axis. The transmission mechanism includes a transmission member for transmitting a rotation amount of the rotary member with respect to the base member to the projection lens and rotates the projection lens according to the rotation of the rotary member with respect to the base member.

An adjustable headlight device comprises a lens having a light input portion and a light output portion, a light reflection control set having a first and a second light reflection members, and a light emitting diode arranged between the first and the second light reflection members. The first light reflection member is arranged under the lens and has a first reflection portion arranged toward the light input portion. The second light reflection member is arranged at one side of the light input portion and has a second reflection portion arranged toward the light input portion. the first light reflection member and the second light reflection member are configured to effectively decrease the light transmission space with the light reflection principle. The adjustable headlight device may make a lighting distance change to achieve the effect of switching a high beam headlight and a low beam headlight.

A lighting device includes a housing including a front opening portion and a rear opening portion; a light source unit including LED light sources and a heat sink configured to absorb and radiate heat produced by the LED light source; a socket formed by an elastic member and configured to allow the heat sink to be fitted and supported in the rear opening portion such that part of the heat sink is exposed rearward through the rear opening portion and that aiming adjustment is enabled by changing a position of the light source unit relative to the housing. A knob used for manually turning an adjustment screw is attached to a rear end portion of the adjustment screw, and the socket is provided with a rib extending along a circumferential direction of the socket and protruding rearward of the heat sink.

The present disclosure relates to illumination systems and devices for a personal transport device. More particularly, this disclosure describes an attachment for the personal transport device that modifies or adjusts light from a light source on the personal transport device. The light source may be positioned within the personal transport device for dispensing light. Without the attachment, the light from the light source is projected in a forward direction. With the attachment, however, the direction of the light may be modified or adjusted to be pointed in a direction and width for a specific driving scenario.
