Review on H7 Headlight Headlights Conversion Waterproof by Larry Lackings

These lamps appear to be very well made. They were easy to install as driving lights. Let me elaborate. Bought for a 2010 Volkswagen Jetta. The description says high or low beam. The Jetta has separate bulbs for high and low beam. The installation guide provided by Revain says they are suitable for both. However, they are NOT suitable for low beam. The way the 2010 low beam bulbs are wired makes it possible that you cannot use LED bulbs with heat and fan sync. Just note that if you have a 2010 (and possibly a different year) Jetta or Golf, these will only work for high beam. You need to get different style for low beam. I'll add photos later.
