Thanks! It's a work in progress. I try to get onto gravel once each day, and have a mini Iron Butt ride and a week long camping trip planned for this summer. I'm running a Denali SoundBomb horn. It is a copy of the Stebel Nautilus air horn, with a few improvements.
The dead LED's in your buddy's tail light are probably cold solder joints. If the light can be opened, a quick touch with a soldering iron should fix them.
