LED headlight bulbs are aftermarket replacements for factory installed halogen lamps. They are developed to make upgrading conventional automotive headlight systems to LED technology quick and painless, resulting in superb performance, premium efficiency and long life. Vehicle headlights are forward lighting systems that provides a clear view of what’s ahead to a driver during hours of darkness or poor visibility conditions while informing other road users of the presence of the vehicle. An LED headlight bulb is a plug-n-play lamp retrofit that is designed to fit the form factor and physical dimension of the legacy light source, has similar light distribution, and follows the same electrical specifications. LED headlight bulbs are interchangeably called as LED conversion kits. Strictly speaking, an LED conversion kit is a product that includes all elements necessary to convert a halogen headlight into an LED system.
