If you have lost your Volt 400 or AMP500 (or just want a spare) from your Brompton, this light will fit onto the Brompton bracket. If you want to fit to a Brompton on you will need:
a replacement dynamo lamp bracket only (code: Q101219 reference: QVBKTFLAMDYN-LED) used in combination with
a CatEye center fork light bracket (#5342440) - this is just for the CateEye adaptor and will not fit without the correct Brompton bracket (we have tried)!
