Bill,

I've used high-powered tail lights and brake lights on my Vanagon for
years and when I recently inspected the internals of my taillight
housings I found that they were distorted from the heat.  Some black
plastic actually bubbled.  Now, my current Westy is a part-time
vehicle, so the amount of time I actually used the taillights is not
that high.

I thought about using the type aluminized adhesive tape HVAC folks use
to seal ducts inside the taillights to increase reflectivity.  There's
lots of heat-and-light absorbing black in there after all.
