Conventional Sealed-BeamHeadlamps:
A sealed-beam headlamp is a one-piece, replaceable unit containing a tungsten filament, a reflector, a lens, and connecting terminals.The position of the filament in frontof the reflector determines whether the filamentwill cast a high or a low beam. The glass lens isdesigned to spread this beam in a specific way. All high beamsare spread symmetrically through beams are spread.
Halogen Sealed-Beam Headlamps:
This Head bulb illumination comes from passing currentthrough a filament in a pressure-filled halogencapsule, instead of through a filament in a conventional evacuated sealed-beam bulb. Halogen lampsprovide brighter, whiter light than conventionalheadlamps.
Service and adjustment procedures are the samefor halogen sealed-beam lamps as they are for conventional sealed-beams.Halogenlamps are manufactured of glass or plastic. Glasslamps carry an “H” prefix; plastic lamps have an“HP” prefix.
Composite Headlamps:
Composite head lamp design uses a replaceable halogen headlamp bulb that fits into a socket at the rear of thereflector.The housing can be designed to fix a single bulb ordual bulbs.
High-Intensity Discharge (HID) Lamps:
HID is the latest development and technology based lamp. This HID lamps produce light in both ultraviolet and visible wave-lengths, causing highway signs and other reflective materials to glow. These lamps do not rely on a glowing element for light. Instead the HID lamp contains a pair of electrodes, similar to spark plug electrodes surrounded by a gas.
Head light:
The primary function of headlights is to provide illumination for the driver while operating the vehicle. This illumination allows the driver to safely navigate roadways and arrive at their destination.
Work sight lamp:
Work site lamps are crucial for ensuring adequate illumination on construction job sites. They provide operators with improved vision and visibility, leading to better and more efficient job performance.
