There is disclosed a forward cooling headlight comprising a body, a lens coupled to the body and a heatsink coupled to the body. There is also a heatpipe and at least one light. The light is coupled to the heatsink, wherein the heatpipe is coupled to the heatsink at a first end, and to the body at a second end. The heatsink draws heat away from the light, via the heatpipe and towards the body. There can be at least one synthetic jet coupled to the heatpipe to aid in cooling the light. In addition, in at least one embodiment, there can be at least two lights with at least two different drivers with a first driver driving a first light and a second driver driving a second light wherein when each of the lights is lit it is capable of generating a different focal point.
