Is there voltage across the wires leading to the light? If so, the light is burned out. If not, check continuity from the ground side of the light to the battery (-) post. If it is good, check for battery voltage on the + side of the light when the switch is on. If there is no voltage there, follow the wiring back through the switch to the battery + and determine where it is good.
