Tongsheng TSDZ2 250w ... 36volt or 48volt?

Very limited current and a risk to the controller even tried a relay and high output led up to 70v in with a cree driver just hated the extra cables

Wow! Nice bike too!

Are you happy to supply the cables though? I much prefer permanently fixed lights to fit & forget.

If you want to fix and forget, connect the lights charging socket to the USB socket.

Because dynamo lights are designed to be permanently fixed - being bolted to the bike means they stay put & don't get casually removed by tea leaves.

Not dynamo but is lockable https://www.decathlon.co.uk/fl-520-front-lock-usb-id_8486893.html backlight available too.

I actually prefer my removable lights but I guess it can be a pain to take them off and put in your bag/pockets when parked up

I'm with you on fitted and wired lights. Wife's KTM eStreet has fitted lights and it's much nicer hitting a button on the controller to switch both on rather than my bike which has separate rechargeable lights.

It's a daft idea to use a dynamo on an electric bike. Think about it!

Am just using the lights, not a dynamo.

Biggest possible issue as already noted is the low current supply (though I'm still planning to fit 6v lights to my TSDZ2).

Exactly that. Anything made for the Dutch usually comes with permanently fitted lights, lock & a rack. You don't unchain your average hatchback & clip lights on it every time you drive somewhere. I had an old Gazelle Dutchbike...got the t shirt...the Dutch know their stuff when it comes to using a bicycle!

That's if it is a low current supply - Peter.Cs lights look like they were drawing a bit - would be nice to know what the supply is rated at.

The high current cree lights in the pic are powered via a relay that connects to the tsdz2 light cable then fused to the battery [also needs diode across the coil ]

Standard output <500ma it is not fused and unhappy at one 6 v led front light and one dim rear light , check out ebay for front and rear set ok in a city with street lights but no good in the dark

Ah I see why using a relay is a good idea then...and looking at the voltage of ebike versions of lights, some stepdown required :/

The one in the pic had cree led drivers, and worked 36v -70v with a day light halo and high beam

Hi Swizz, I have simply used the lighting cable that came with my 48v TongSheng kit. The speed sensor had a "Y" dual socket so plugged the sensor into the one and the lighting cable into the other. Bought some low cost front & rear lights and it all works a treat . The VCLD5 provides DRL & full output all powered from the main battery. I only needed the lights for safety reasons and to assist on darker evenings, definitely NOT dark forest trails!! Lights cost me around £25 and I did add some extra support to strengthen the spade connectors on the front light and the push-fit connectors on the rear by applying some silicon sealant and insulation tape. I am not sure whether I should of added a fuse as I feel I have sufficiently strengthened the cabling to avoid potential shorting and risk damage to the controller. I am sure someone will be along shortly to correct my errors.
