Now that daylight arrives somewhat after my usual morning departure time, I've put my dyno hub wheel and Supernova E3 back into use on my commuter.
I noticed my light would cut out intermittently, so I checked my connections, sanded off any crud build up and crimped the female connectors to insure a tight connection and still no light. Or rather, at best, the hub produces just a small amount of light, less than the stand light function outputs when it worked. I've checked the hub, it seems to be producing power, so am thinking its the LED failing?

Anyone have other ideas? Is bulb replacement a user task or do I need to send my light to Peter Jon White?

Thanks

Steve- in the dark, again

I'd contact either Peter White, or the manufacturer - sometime they accidentally send out defective stuff, and will replace it for free.

With an LED, you pretty much never need to replace the bulb, if it's working at all I suspect that is not going to fix anything.

I suspect a wiring problem. If you have enough wire I would cut a couple of inches off of it, and attach new connectors and try again.

Yep.
