Not sure if your question is in regards to the product (e.g. resistor packs), or to the entire project. Yes, product questions go back to Cyclops, they'll be very helpful. As to the project itself ....
I picked up some LED H1/H7 replacements off Amazon. The install was ~~~ difficult ~~~. I tried initially to install the new bulbs using BMW's approved method, but I didn't have the hands of the 5 year old who wrote those instructions. Instead, i have the big, adult sized hands. After a week of playing around with it, I finally decided to just get the job done, and pulled the headlight assembly out of the bike. If this looks scary, well, yeah, it is, but it's not that difficult to do.
... to get to this:
... which flipped around, looks like this:
As I mentioned earlier, I started out in half measures, removing the left speaker cover and speaker, to see what was hiding underneath (pictured below, left high beam & H1 bulb through the access port). While I could SEE what needed to be done, I couldn't reach it. I was able to eventually remove both retaining clips on the H1 bulb, but could also see that I'd never be able to position the LED's bulb's bracket, without dropping it down into the light assembly (which would require tearing everything down anyhow). When I finally had the assembly out of the bike, I realized pretty quickly I could never have successfully installed these things without removing it, due to both the brackets and bulb size, and connecting up the wires (which required using provided jumper wires, because the bulb's pins were up against the edge of the plastic access port/hole, making it impossible to attach the BMW's light plug)..
I have a full folder of directions, mine and BMW's (i.e. service manual), plus some pictures that I can share with you if you think you need it. I won't publish it here, since it includes copyrighted BMW documentation excerpts (in PDF form). Send me a private message with an email address, and I'll send you the files in a ZIP file. The biggest problems I had were in understanding how to remove a couple of BMW's plastic rivets (without breaking them). The one on the side fairings has a center section "pull out", which releases the rivet stays (i.e. plastic fingers), while the one on the nose fairings looks like a Phillips screw, which in fact, does screw outward to release the rivet stays behind the plastic. (BMW doesn't explain EVERYthing in their documentation at the "village idiot" level, i.e. my level.)
Probably more info than you were requesting, but then again, what do ya expect when the local village idiot responds to your post. 🙄😏
