Connector/Adaptor: From Male to Female Conductor Waterproof trail connector (10"long, 10AWG) for E-bike and Bike light

I've used this product in both the headlight and running lights of my bike lighting system. Headlight My primary light is a 30W Philips EnergyAdvantage (24 degree narrow flood) MR16 in an Optronics housing, driven by a 14.4V NiMH battery (4200mAh) from batteryspace.com. Battery is mounted in a CageRocket, with hole drilled in the side for a waterproof switch from batteryspace. Connectors are the very rugged "waterproof" ones from batteryspace. Unlike my v1.0 homebrew light project, which used quick-and-dirty but ugly crimp connectors, all connections on my v2.0 are soldered and shrinkwrapped. I've been using my running lights for a couple years now and they're working out great. I have four Piranha automotive LED side marker lights on my bike: an amber one on each fork leg, and a red one on each seatstay. Each of these is about 2" long, contains two emitters, is very bright and consumes around 1/2 watt. I have four more of these units (in addition to $20 worth of DOT reflective tape) on my child's Chariot Sidecarrier trailer, with connectors that let me tap the trailer into the bike's running lights whenever I'm using it. Driven by a little 2000mAh 12V pack from batteryspace that I've had for a couple of years (current model is 2200mAh), this system has performed flawlessly for nearly 2 years of year-round (yes, including summer) commuting. I'm not using a switch, since that's been a failure point for me in the past: I just plug the running lights in at the beginning of a ride, and unplug them at my destination.
