Wanting to get some bright LEDs for the headlights and be rid of the incandescents I didn't find many options other than the ebay "led" bulb. For less cost I used the H13 LED bulbs that have high and low beam. Bulbs I used are the Nilight 6500K cool white H13 from amazon. I removed the housing and removed about 4mm of housing plastic and the lugs from the H13 matched the 650i.

Going to want to leave about 8.5mm of plastic and the lugs will engage. Use sandpaper as you get close and you can adjust plastic removal so the lugs are snug but not too tight and at risk of breaking the plastic lugs.

My LEDs were snug and made a good seal. I added a couple of spots of epoxy to resist the vibration of riding and to provide support.

I reassembled and cut a narrow slit in the back black housing cover so the Led wire could run through.
I wired the Low and High beam circuits with separate 12v automotive relays. The stock positive feeds for low and high will power the separate Low and High relays with direct 10 amp fused power that's direct from the battery to the LEDs.
These Leds fit well and do not touch the plastic lens.

The side marker lights I used a turn signal blade style LED that fit great and is also very bright.

Night ride - very bright

Yea I've seen those bulbs. The h13 are much brighter and much cheaper. I've got an off the shelf solution for now on. If you're not very good with your hands or like to modify then that is an option.
