Vintage BMW Motorcycle Owners

I am thinking of converting my turn signals to running light/turn signals and am looking for some advice on the kits from from Run-n-lites. There seems to be two versions, the standard double filament bulb kits and the LED Lite-buddies. Does anyone have any experience with either of these? Do the LED versions need a special signal relay/blinker? Do they fit the ‘74 metal turn signal housings? I currently have amber on both front and rear should I switch to red on the rear, and are red lens available? Are there other kits available besides those from run-n-lites?
