1. A lighting apparatus for a vehicle comprising:
a housing comprising a mounting structure;
a lighting package comprising:
at least one circuit board;
an operative connection that allows for connection to an electrical system of the vehicle; and
a filament located within a lens, wherein said filament comprises at least one light emitting diode (LED) and said light emitting diode is soldered onto the at least one circuit board, wherein when a wiring harness is connects the lighting apparatus to the vehicle and the filament is operated such that the lighting apparatus produces an upper and lower beam, there is no warpage on the lens of greater than 3 mm when measured parallel to an optical axis at the point of intersection of the axis of each light source with the exterior surface of the lens;
a flexible metal heat sink to dissipate heat caused by the at least one light emitting diode;
an adjustable collar; and
