The Stopper is great. I've installed this light on my R1 and SV650. Adds tremendous braking and running light visibility, especially at night.
This light bar greatly increases the visibility of my tail and stoplight. Friends are very interested in buying one also. Installing it took a lot of time on my Suzuki Boulevard, but it was well worth the effort. I soldered the wire splices, but next time I'd try PosiTap wire splicers.
This unit was easy to install. It came with stainless steel allen wrench bolts and stainless locking nuts I put one on the Honda Hawk as a break light and two on the KTM EXC 380 one as a running light and the other as a break light. If you fear being rear ended install one for peace of mind! It is very bright and grabs attention from those four wheelers on the road.
