Ok so I'm a bit miffed at this point about cycle-gears after-market blinkers. I purchased a set not too long after getting my bike. Within the last month both of them have been on the frits. One, I have no idea why it stopped working...or started working again. It acted like there was a loose filament, but that wasn't the problem. The other side...cold solder joint on the bulb-housing (actually they soldered the wire to the spring that helps retain the bulb in the housing) Since I heat-shrank...
