Please be aware that the type of rear light used on your e-bike is directly determined by the model of the controller with lock.
To avoid wiring issues or incorrect connections, make sure to confirm the exact model of you controller with lock and match it with the correct rear light version.
All controller with lock are compatible with wiring harnesses with lock.
(In other words, if your e-bike uses a Half twist throttle with a key ignition, it is compatible with all controllers with lock listed below.)
However, the wiring and version for the tail light differs depending on the controller.
ZN-JN03-9-S (Controller with Lock)
New Tail Light → ✅ Direct connection, no adapter cable required
Original Tail Light → ⚠️ Requires Male Adapter Wire
ZN-JN04-9-S (Controller with Lock)
New Tail Light → ⚠️ Requires Female Adapter Wire
Original Tail Light → ✅ Direct connection, no adapter cable required
JN-LD9G003# (Controller with Lock)
New Tail Light → ✅ Direct connection, no adapter cable required
Original Tail Light → ⚠️ Requires Male Adapter Wire
Before connecting or replacing any parts, always verify:
Your e-bike’s throttle grip type (with or without keyhole)
The model number of the controller
The version of the Tail light (new or original )
Improper matching may result in non-functional rear lights or electrical issues.
