My bikes are, for the most part, all weather day/night machines. Mounting a taillight to my CETMA cargo bike was no problem. I used one of the Radbot lights I reviewed a few weeks ago. a front light was a bit more hassle. Putting a light on the bar didn’t work very well as the cargo box and passenger [if I had one] got in the way. So I mounted a Thorn Accessory Bar I had in my spares bin above the front wheel.
This worked great. There is room for two Dinotte 200L-AA lights or just about any other bike headlight that attaches to a handle bar. The mount is very secure and doesn’t get in the way when I don’t need to use it. You can of course achieve the same effect with an old stem and a cut down section of handlebar.
Dual Dinotte LED lights provide a ton of light up front. I added a some battery powered glowstix for some bling. The CETMA was a total chick magnet…=-)
