CT1 plug pair on the CAc30 extension — the same light-side plug as on our system cables with CT1B.
We verify connector compatibility ourselves (as of 2026-07-30). That means the mechanical and electrical plug interface — not further properties of the drive or the headlight. Before installation, check the requirements of the drive system and the lighting. If you are unsure, contact us or have the work done by a specialist workshop.
The same CT1B system cables apply as for headlights with a CT1 plug: Bosch 1300 mm, Shimano 1300, 1900 and 2300 mm, Yamaha 1300 mm, Avinox 400 mm, plus the 300 mm CT1 extension. Open-end cables without CT1B are for other connection types — they do not replace the HIGO plug.
