Lighting and Horns: Description and Operation

GENERAL INFORMATION
Each vehicle is equipped with various lamp assemblies. A good ground is necessary for proper lighting operation. Grounding is provided by the lamp socket when it comes in contact with the metal body, or 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 Mopar Multi-Purpose Grease or equivalent.

SYSTEM OPERATION
Daytime Running Lamp Module (DRLM)
The headlamps on vehicles sold in Canada, will go on when the ignition is turned ON. The module must also receive a signal from the engine controller. This provides a constant Lights On condition while the vehicle is rolling. The lamps illuminate at less than 50% of normal intensity.
