Unless you already got the VW LED OEM lights, then it isn't an easy $$ fix
I've noticed that people have reported an increase in light output with the H7 upgrade, some are happy, some are disappointed.
While i would have liked to go that option, spending $1000 AUD for a set of H7, doesn't seem worth it, if it didn't workout fo me.
I liked the projector retrofit, but the new RHD projectors seem to be awhile away, so i decided to order some LED Bulbs until someone brings out a full Aftermarket LED headlight unit.
All you can do, is review the light patterns from the bulbs fitted here by fourm members and decide if it is worth it for your use and application
