Great Replacement
The good. A perfect fit for my left turn signal lamp. 2003 BMW 330XI. Works and looks good. Has weather seal. We will see how it stands up to the Florida rain and car washes. The bad: As you can see in the picture the right lens retainer clip came in broken, Probably damaged in shipping. No big deal I just needed the left, I'll probably just super glue it and store it as a spare. Overall I got my moneys worth and I'm happy. Product was as described and arrived on time. I will buy from this seller again.

Cheap enough to not really worry about
They fade to yellow pretty quickly, and get moisture in them. But they look good at the beginning!
