Well I've got all on my mouth Tain bikes and road bikes over the years. I've got hid on my road bike for commuting. Geez it must be 10 years old. It traitted as i recall a tailtech motorcycle accossory light. But modded to a lithium ion battery. It's nice as we're the light and motion / nite rider version. But really led is so much easier and cheaper. I use two lumina 950 boost $68 each. And getting a third.
The Larsen led stuff is very stout if u wirenit correctly. Please refernto my earlier post.
But I don't doubt u canake a better mousetrap
