1. A light emitting diode lighting assembly mountable to a curved surface comprising:
- at least one light emitting diode;
a circuit board for providing electrical current to said at least one light emitting diode;
a molded polymer section surrounding and insulating said at least one light emitting diode against said circuit board, wherein said molded polymer section is polyamide;
a lens having an inner surface, an outer surface, a perimeter defined by a circumferential ledge, and a lens cavity formed therein, said lens being positioned over said molded polymer section and circuit board such that an air gap is present between a top surface of said at least one light emitting diode and said inner surface of the lens;
a flexible molded housing surrounding the perimeter of said lens and said circuit board thereby sealing said lens and said circuit board, while maintaining the air gap between said top surface of said at least one light emitting diode and the inner surface of said lens, wherein said flexible molded housing is polyamide;
an adhesive material positioned against a back portion of said flexible molded housing for attaching said light emitting diode lighting assembly to said curved surface;
andwherein the flexible molded housing includes a pair of flexible extension wings elastically deformable up to a radius of curvature of 4.5 inches for curving such that said light emitting diode lighting assembly may be adhesively attached to said curved surface.
