Turn Signal Adapter Plates


The OEM signal lights on the front end of your Triumph Modern Classic are large enough to be seen from space. While Hinckley's safety first intent is undeniably righteous, the bulbous aesthetics leave a lot to be desired. The British Customs Turn Signal Adapter is a quick and easy solution to easing the fitment of the aftermarket markers your style demands. By modifying the mounting point to accommodate just about any aftermarket lamp, the BC Adapters are custom-cut in just the right shape to fill empty spaces and drilled to provide a solid mounting point for lamps with up to a 10mm mounting shank. Laser-cut for a precise fit, the adapters are made from black anodized aluminum for durability and weather resistance.
