I was going to buy the Sylvania Silver Star lights, but as I was checking their web site, they listed the 9004 bulb with a Max. wattage of 50/70. The OEM bulbs from Mercedes are 55/60 so does that mean I will blow out these Silver Stars? Also, I called Performance Products and they said that my car uses an H5 bulb which is also known as a 9007 bulb. In previous posts, other members have stated that my bulb is a 9004 so is Performance Products wrong? The 9007 bulb is also available in the Silver Star with a Max. wattage of 60/70. So which bulb can/should I be using? Please forgive my ignorance, I'm just a bit confused.
