euro lights are absolutely awesome, it is the only way to see at night.
i attaching a picture and a couple of links. PLEASE only buy hella or bosch, oem mercedes lights. there are numerous quality control issues with off-brand/aftermarket cheap lights and this has also been a very hotly debated subject!!
do a "search" here on euro lights. there are hundreds of posts.
