Description and operation

Lamp systems

Each vehicle is equipped with various lamp assemblies.

A good ground is necessary for proper lighting operation. Grounding is provided through a separate ground wire.

When changing lamp bulbs check the socket for corrosion. If corrosion is present, clean it with a wire brush and coat the inside of the socket lightly with mopart multi-purpose grease or equivalent.

Headlamps
