The XML2's have been discontinued and replaced with our new, USA-made SLF model. It's a great match with OEM HIDs and will produce a much better output pattern than the previous XML2.Am I missing something? I don't see the xml2's on your website anymore for the 2015+ STs (I have the 2017). I have the factory HIDs so was hoping to get the 5000K to match (possibly 3K...haven't decided between yellow or white to match the headlights). Link perhaps?
The SLF is also smaller in size, so it will fit better on the 2015+ Focus STs than the XML2 did. Here's an example with the SLF installed on a 2015 Subaru XV Crosstrek:
