Lucas turn signal indicators Norton Commando — matched pair (Part# 54057567) of replica Lucas-type long-stem turn signal indicators for Norton Commando, BSA and Triumph.

This is a matched pair of replica Lucas-type turn signal indicators (part number 54057567) as originally fitted to late-model British motorcycles including Norton Commando, BSA, and Triumph. These are long-stem style indicators that match the classic look of the original Lucas units, making them the correct choice for restoration or period-correct upgrades.

The Lucas 54057567 turn signal indicators feature a 5-inch long stem that positions the indicator head outboard for good visibility. They are sold as a complete pair – one left and one right – with mounting hardware included. These replica units use modern internal components for improved reliability over the original Lucas electrics, while maintaining the authentic vintage appearance.

These indicators are compatible with 12-volt electrical systems as used on Norton Commando 750 and 850, BSA A65 and A75, and Triumph Bonneville and Trident models. They mount using the standard Lucas-pattern threaded stem and are suitable for front or rear use.
