1. A method of forming a Light Emitting Diode (LED) assembly, the method comprising:
drilling a first through hole in a printed circuit board, wherein the first through hole attaches the printed circuit board to a housing;
determining a first fiducial based on the first through hole on the printed circuit board,
wherein the first fiducial is used to determine a LED module placement accuracy within the printed circuit board;
after determining the first fiducial, determining, using a plurality of images of a LED module, a center of a LED emitter of the LED module, wherein the LED is integral to the LED module and the center of the LED emitter is different than a center of the LED module;
placing the LED module on the printed circuit board based on the first fiducial and the center of the LED emitter of the LED module.
