Brompton hub dynamo rear wiring

Main wiring loom, for Brompton (SON, Shimano and shortly SP) hub dynamos with LED front lamp (also works for Halogen with a small modification)

This double wire cable connects to the front lamp and feeds power to the rear lamp

The normal double core dynamo cable is extra protected by an outer sheath

In the download section at the bottom of this page is a datasheet showing how the hub dynamo and this cable should be fitted / routed


There are two spade type connectors on one end of the cable for connecting to the

One end has bare wires for connecting to the rear light (the most recent ones we had, came with cable on the bare wires to help prevent them fraying when threading through to the back of the bike - to the rear light)

Specification / Details

Approximate cable length: 180cm

Can be used for any Brompton-supplied LED hub-dyno-lamp, but if for use with a pre-2011 LED dyno-lamp (with integral main-loom), tab-connectors (QVTAB-DYNFLAMLED) are needed to modify lamp-wiring.

Complete with cable ties for securing the cable to the bike to avoid fouling
