TECHNICAL FIELD
The present disclosure generally relates to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to the construction and mechanism of a headlamp for two-wheeled vehicles. Further, embodiments of the present disclosure disclose a beam adjustment mechanism for a headlamp of a vehicle.
TECHNICAL BACKGROUND
Generally, vehicles such as, but not limited to, two-wheelers such as bikes, scooters and the like are provided with a headlamp for directing light on the road for visibility in dark. Headlamp forms an important and integral part of the vehicle. While driving in dark, headlamps enable the driver to find and navigate the way and detect any oncoming vehicle or any sort of obstacle. A headlamp generally comprises of a housing and a lens which together create an enclosed compartment or a chamber. This chamber contains a light source, such as an incandescent lamp, a light emitting diode (LED), a high intensity discharge (HID) lamp, or a projection lamp, electrically connected to a power source. The chamber may also include a reflector surrounding the light source. In some cases, the housing itself may be made reflective.
Such headlamps deliver light into two patterns namely low beam light and high beam light. Such patterns have a pre-defined range of light and a user can switch to either low beam or high beam for proper visibility. The mechanism to switch between low and high beam light varies and is based on the vehicle manufacturer. Due to movement of vehicle such as bikes on a rough terrain facilitates loosening of the fastening means located in the head lamps. The loosening of such fastening means results in irregular deviation or scattering of the light beam coming out from the headlamp of the vehicle. Therefore, after a certain period of time the reflect light beam gets scattered and fails to illuminate the front portion of the vehicle.
Besides this, such headlamps are provided with a screw and nut arrangement to adjust the headlamp position by which the position of light thrown can be adjusted. However, one problem associated with such headlamps is that the screw and nut arrangement are installed at an obscure location. The screw and nut arrangement is not readily visible to

the driver to adjust the headlamp effectively, rather the arrangement is located in a remote location of the headlamp assembly.
For adjusting such headlamps, a user has to perform operations such as opening the headlamp, actuating the screw/nut arrangement and closing the headlamp. This requires labour and a lot of time, thereby the user faces difficulty.
In view of the above, there is an immense need of an adjustable headlamp that overcomes one or more limitations of the existing headlamps.
