The headlights are on the engine 12 volt system. We suggest that you check the voltage at the headlights. If the voltage is above about 13, replace the headlights, perhaps with high performance replacement units that are available in the after market. If the voltage is below 13 volts, check the voltage at the alternator and adjust upward if set at less than 13.8 at the alternator. If the voltage at the alternator is 13.8 volts or better, check other points between the alternator and the headlights to determine where voltage loss is occurring, and repair or rewire to increase the voltage at the headlights. A tip to decrease voltage loss to the headlights: provide power to the headlights through a relay installed close to the headlights rather than running the headlight power through the switch on the dash. Use the dash headlight switch only to operate the relay.
