[RBW] Re: Rewiring a battery powered taillight for use with a generator hub?
Standlight function is key, and while my soldering skills are passable, my love of schematics/acquiring not tiny enough electronics add-ons, is nil. Thanks for the advice all, new toplight is on the way, battery powered is moving to the trailer.

I generally agree; it ain't worth it... UNLESS of course you're retro-fitting to achieve a particular look. I'm attempting this for a project where I want to use a SOMA chrome fender-mounted light (Anton I wish I had seen your light first!!)... I gutted the light and retrofitted the dyno-guts from a Spaninga light into the SOMA... Nothing glamorous, but seems to work, and will hopefully give me the look I wanted.

Hi Kai, It's technically feasible, but probably not worth it. First you'd have to determine what voltage your light was built for (how many batteries does it take, what type, and how are they connected-- series or parallel?). Dynamos output 6V nominally. Then you'd have to create a bridge rectifier circuit to convert the AC generator output to DC, and you'd have to fit this circuit somewhere inside the taillight. That would be the minimum. You'd also want to install a couple of diodes and rechargeable batteries to allow the batteries to charge while your hub is generating power. It's all very simple but takes up a lot of space if you build it yourself. You're probably just better off getting a dedicated dynamo light.

I did it to a BM 4D. It was pretty easy with the only downside being I never got a proper RC set-up so as to have stand-light capability. It's been some 5 years and I haven't thought about batteries a single time since. I'd say if you've worked on electronics previously have at it. It's been done and I'm sure there are how-to write-ups on the Internet. If you don't know which is the hot end of a soldering iron, then maybe it's not the project for you, unless you're looking for an easy project to learn on, in which case this may well be a perfect one. LMK if you need help finding a how-to.
