The H6 and H7 are essentially interchangeable. These are the most common batteries in modern cars and fit most every European cars as well as many of the more modern American cars.
The H1 is used for the high-beam light, whereas the H7 is used for the low-beam light. The H1 and H7 are both single-beam lights and use a single filament to create a fixed beam.
The light output is higher with H7 systems than with the H4 ones because two lamps interact. But since H7 systems require four bulbs instead of two, and bulbs should always be replaced on both sides at the same time because of their similar lifetime, H7 systems have a higher cost factor over time.
