Based on this review and excellent installation instructions... I got these and Love em'. They look great and the plug-n-play installation sold me. It seemed that every installer in the area wanted to take my front bumper off and charge several hours of labor to do the install. No need, although it doesn't hurt to have a friend with small hands around to access the area where they are installed.
I was undecided between the 12W and 20W... purchased the 20W and made the right choice. The pics posted do justice to the look, including in direct sunlight. FYI
