Testing

Headlamp Diagnosis:

Viper vehicles built for Canada export are equipped with a Daytime Running Lamp (DRL) system. The DRL system operates the headlamps at 50 % illumination with the headlamp switch OFF and the engine running. The DRL system is controlled by the Daytime Running Lamp Module located on the inside of the right front upper frame rail above the stabilizer bar. The DRL module overrides the headlamp switch when the headlamps are turned OFF The headlamps operate normally when the headlamps are turned ON.

When a vehicle experiences problems with the headlamp system, verify the condition of the battery connections, charging system, headlamp bulbs, wire connectors, relay, high beam dimmer switch and headlamp switch.
