I have a BMW E46 construction year 2000. I want to change my low-beam and high-beam bulbs. The type of bulb is H7. From the factory the car has Philips bulbs. I want to tell me which is the best bulb. I am between osram silverstar and philips vision plus. Which is the best between these two ? What about blue bulbs? Are they better from the two i mentioned above ? Is the philips blue vision better than philips vision plus ? I want the best visibility and safety.
