I picked up a BLT Firewire 4.0 headlight for my bike in January 2009 (and has had maybe 6 months of use in that time). It came with some pretty crappy mounting hardware (a velcro strap to attach the light? really?) but that was easily fixed with some hardware from the bike shop. The velcro straps holding the battery case to the bike frame broke long ago. That was easily fixed with a length of spare inner tube and a couple of zip ties. But now the wire connecting the LED light to the battery has worked loose, so it doesn’t work at all. No amount of zip ties will fix that. The light is dead. I’ll never buy a BLT light again. $150 down the drain.
