NeezyDeezy and others who have or are considering Zenon strobe units: I have used the same now discontinued Radio Shack strobe for close to fifteen (15) years. The first, all $15.00 of it, failed in a few weeks. When I opened it I found a large (thumb joint sized) capacitor attached to the sircuit board by only two lead wires. I simply brought another unit, carefully opened it and used gobs of simple translucent silicone caulk to brace it. Reassembled it has lasted since the early 1990s. The flash intesity is far FAR superior to any other flasher I have seen. It exceeds the flashers you see on some forklifts one sees in warehouses. One night my headlight failed and I finished the ride down the unlit moonless bike path using the forward part of the 360 degree strobe. When I rode the night rides with the Orange County Wheelmen in Southern California I was told to ride at the back of the pack, my taillight hurt their eyes. If it ever was stolen or broke I would check out the All-electronic strobe immediately, opening one to check for loose parts.

It uses a watt or two, trivial with my 144 watt-hour battery.
