Just some input here, buying the cheaper bulbs up front is ok, they work for a while and then start losing leds.
Ive been making these kits for Hayabusa's for almost 10 years.
I also have done many sportbike mirrors, the same way, just need more patience to deal with them!
I have them for Goldwings now too.
Yes i have made changes, to what ive sold. Because i have always sold my stuff with a 2 year warranty on the bulbs and life on my install kits.
Only thing i wont cover, is if you wreck your bike and the sockets are damaged, thus why i charge what I charge for my kits.
My kit is also 100% plug and play also.
The socket you posted will work, need some modding, and are a knuckle buster to get in and out.
Good Luck, it a Great mod and works great. You might find a some feedback when you shut the bike off on some bikes, but not all. Some will click and flash 6 time every now and then, im still tring to narrow this down.
Good Luck
