several brands that are available - Ziza, or i purchased mine through www.autolumination.com and just look up the Festoon type (middle of the page) w/ canbus attached.
I bought the 3 SMD pad and they are super bright - still working after 2yrs without issue.
Parking lights same thing... just look up the T10, 168, 194 LED w/ canbus - Autolumination or ZIZA again..
*Autolumination has them for cheaper
Lastly - www.performanceleds.com has an MK5 kit too - good customer service as well
