Adding lights to Swytch?

Hi,
I’ve purchased a Swytch kit, and as I’m installing it onto a bicycle that previously had a Shutter Precision dynamo hub and corresponding lights, I can’t help but feel that in terms of lights I’m getting a downgrade as I have to replace both lights with battery-operated ones, whereas there’s a huge battery which could power them as well. Has anyone tried to modify the Swytch setup to make it power lights as well?

Thanks in advance for any ideas or suggestions.

Personally I like having independent lights (battery leds in my case) with my much modified Swytch Mk 1 kit.

If the battery is a generic two wire connection, then if you have basic wiring skills you can take a 36V feed out of there, fuse protect it, and use a 36V to whatever voltage you need DC to DC converter and run the lights from there.

Some lights will work 12V-80V. I've got this one soldered to my ebike battery (two wires) via an inline blade fuse and waterproof handlebar switch. It's one less thing to forget about charging before going for a ride.


I've ordered another, to make red for use as a rear light.

Those connectors are already waterproof, but yeah, why not.
I don't trust anything claiming to be waterproof, at all.

BTW, thanks for this:


Very handy. I was trying to crop an extremely large image a few years ago to make a lot of tiles from that one image, to assemble after enlarging and printing out, to cover a wall, to trace that image onto the wall, to then paint. Photoshop adequately resourced did it in the end, but jpegtran would do the same with a far less powerful computer.

Options are less limited with dumb batteries:
