I have a 2002 Ford Ranger XLT, 3.0 ltr V-6, 51,500 miles. The truck runs great. When the lights are on at night I notice a pulse almost like a fast heartbeat in all of the lighting. Headlights, tail lights, dash & interior dome. The truck seems to be idling fine & this problem occurs no matter the enging RPM. The pulse speed doesn't change. Any advice?

Hi Greg
It sounds like you may be missing a ground, check your battery cables for corrosion and clean them first and follow all grounds from the battery to make sure they have good clean connections, if the whole lighting system is doing it its gotta be something in that neighborhood
