A sheet metal panel that covers the area from the rear-door opening
to the taillight area, and from the bottom of the surface to the
base of the roof, or from the headlamp area to the front-door opening,
and from the bottom of the surface to the base of the hood.
Quartz Halogen Headlamps
A headlamp bulb having a quartz envelope holding the tungsten filament
and filled with an inert gas containing iodine or another of the
five halogen gases. The gas serves to remove the tungsten deposits
from the bulb wall and redeposit them on the filament, preventing
blackening of the bulb surface and reduction of light output. This
kind of cycle requires very high filament operation temperatures
which necessitates the use of quartz instead of glass. These lamps
produce more lighting power per watt of electrical power than standard
sealed beam headlamps.
