I just installed them on my 2001 Honda Shadow Spirit 1100 last night. My wife wondered why I was gone for nearly an hour. Installation was quite easy, the biggest challenge being hiding the bulk of the wiring harness. I took the tank loose at the back, bundled the wiring harness with cable ties, and secured it to the frame under the tank.
Forward lighting is so vastly improved, there's no comparison.
Thanks for making such a great product. The quality is obvious and other riders often ask me about the product. When I took my first evening ride after the lights were installed I was amazed at the difference. The amount of light and the effectiveness of the pattern make me feel much safer. I recently took a 1200 mile tour around Lake Michigan.
