There are so many LED headlight bulbs out there that it's hard to find a good one. This one was perfect for me. It's not too big so fits easily in the MK6 Jetta GLI low beam housing with the lid closed, it has a built in decoder and the colour/light is perfect. It's not that annoying blue light that blinds others and doesn't light up the road. It's sharp, very bright on the road and doesn't shine too brightly to blind other drivers when they're looking at the car. I will definitely use them for my high beam.
