Well aware of the search function and seeking a straightforward, easy answer. Own a 2011 E91 wagon (non-Xenon?) and seeking an upgrade for the old and fairly dim OEM headlights bulbs as my wife complains at night!

Seen some usage of H7 from Phillips or Osram?

I use the Morimoto 2 Stroke 3.0 LED bulbs in those same housings, and they're terrific.

Any comments or recommendations on the kit (retrofitsource?) and install?

That's where I bought them, yes. Install was very straight forward; they use an installation collar with gets mounted first, using the spring clip in the housing. The bulb then slides firmly into the collar. Be sure to align the bulb vertically (LEDs at 3 and 9 o'clock) so that it mimics an incandescent bulb. When mounted correctly, the beam pattern is excellent, with a sharp cutoff, only with significantly more light output than incandescent bulbs. Proper mounting also ensures that you will not blind anyone.

You will also need the GTR Lighting PWM modules to prevent strobing and a bulb-out error message.

One nice additional feature: if you use the high beams as DRLs, the bulbs can operate at reduced voltage and will dim just as incessant bulbs do.

This can probably be achieved by coding the FRM rather than using additional modules. Both PWM and error checks are controlled via coding - factory Xenons have PWM and cold monitoring disabled in the FRM.

I don't think of that at the time, but yes, I bet that will work perfectly.
