1. A vehicle lighting assembly, comprising:
at least one light emitter;
a substrate having a first side on which the at least one light emitter is mounted, and a second side remote from the first side and including a thermally conductive material;
a heatsink adjacent the second side of the substrate, the heatsink including a base defining a surface extending in a flat plane parallel to and spaced apart from the second side of the substrate with a thermal interface material disposed therebetween, the base defining an aperture exposing a portion of the second side of the substrate wherein the heatsink further includes a plurality of fins extending from the surface of the base, away from the substrate, and defining venting passages between adjacent fins of the plurality of fins; and
a blower fluidly engaged with the heatsink to drive air through the heatsink, into the aperture, across the portion of the second side of the substrate and substantially entirely out through the venting passages between the plurality of fins.
