Dynamo light not staying on

I'm having some issues with my dynamo/light combo, but I'm absolutely hopeless with electronics.

Dynamo - https://it.aliexpress.com/item/32907761572.html
Light - https://www.bike24.com/p238271.html

The light is housed in an old retro-light - partly to keep the look, and partly to keep it dry as apparently waterproofing was sometimes an issue with the IQ2. The light also has a light sensor, which may be turning it off under streetlights? This would seem like a strange design flaw.

I believe the light has an internal battery, which seems to be charging up somewhat, but not remaining on. How do I go about testing it? Or is my dynamo simply not powerful enough for it?

  • Just found this: is it still a problem?

    I'm wondering if by rehousing it inside the retro light, the internals of the retro light are reflecting back to the light sensor and therefore it believes it's daylight.

    Hi, I hadn't connected it up quite properly. All working great now.

    I do also think you're right about the light sensor, as it will often flick from high-beam back to regular without me telling it to. However to me that's a price worth paying to keep my retro aesthetic :)

    Cool. I'm currently looking at a pair of retro style lights to power from an external battery for my cargo trike, and am considering buying a really cheap pair and sticking solarstorms & Fresnel lens's in , as you originally did..

    If your budget can stretch to it, I would recommend the dynamo set up. One key reason is because this dynamo has a separate on/off switch, which I have on my handlebars. Before, I would have to keep opening and reaching awkwardly into the light to turn it on and off. Dynamos are also just brilliant for not having to worry over charging things - just get on and go.

    Aye, for a normal bike it's definitely worthwhile, but I'm considering converting the cargo trike to a rear wheel motorised e-bike so this is an intermediary step in that direction.

    Of course, the right thing to do is to just buy a proper e-bike, and no worrying about the conversion....
