The alternator is on it's way out.
You probably have either a grounding issue, or insufficient current.
It's probably the voltage regulator inside the alternator. Sometimes, your headlights pulsate from your vehicle drawing too much power from the stereo electronics. This is often the case with a vehicle carrying heavy amounts of amplifiers and heavy-hitting bass. Another idea would be to check the voltage regulator or the alternator. The alternator is what creates the vehicle's power (like a generator) and the regulator simply regulates the power that is sent from the generator. If the either of these are having troubles, this could be causing the flickering lights. I would first check to see if the belts that turn the alternator are loose. If they are fairly loose, then your belts are causing a pulsating power to be created. Think of it like peddling a bike only half of the time. It would cause a speed-up and a slowing down. In turn, if the belts are pretty tight, it's likely your problems are being caused from the regulator not regulating an even flow of 12 volt electricity to the car. The headlights merely flicker because they power flickers from going up to 100% and down to say 80% and so on.
If your lights pulsate while the car is running in your E320, you probably have a problem with the alternator or distributor. This type of issue is most likely electrical.
They pulsate because they are being gorged with blood. This occurs when the heart pumps excess blood into the penis. The heart beating causes the penis to "pulsate" which is actually just a slight vibration (wiggle). If it is actually pulsating, getting bigger and smaller, it might be because he is overly excited or has a blood flow problem.
The music at the concert made the crowd's hearts pulsate with excitement.
The voltage regulator in the alternator can cause issues like this when they start to go bad. The voltage regulator is an integrated part of the alternator and cannot be replaced, if it is bad, the entire alternator must be replaced.
You can feel the blood pulsate through the vessels in the temples of your head. As Carnival approaches, the night life of Rio begins to pulsate with increasing energy. Most lasers are designed to pulsate rather than to shine continuously.
because a main artery flows through there. It's your heartbeat making it pulsate.

They pulsate with each surge of blood from the heart with every contraction as the blood is under high pressure.
