I know it's a pain, but if you go through the thread, you'll find a link to a previous post of mine from when I fitted mine a couple of years ago. There is an embedded video to illustrate them.
I started with resistors on the switchbacks, but later switched the flasher unit for LED compatible. Also converted the headlamps to LED.
I love the clear lenses on the bike. Thanks Ad.
As for the rear, I fitted a brake strobe, in place of the rear reflector, and added additional running and brake LEDs to the Givi box (previously unlit). I did switch the main rear lights to LED on my '91, when I had it, but felt the incandescent were more effective, so didn't do this on the '01.
Very happy with all my lights now, certain I can see, and be seen.
