DENALI Plug & Play 194 Marker Bulb Trigger Wire Adapter

This adapter is designed to prevent electrical accessories from interfering with the electrical system on late model BMW, Ducati, and other European motorcycles with a Can-BUS electrical system and a "City Light" 194 marker bulb in the headlight.

It includes a diode for built-in reverse polarity protection. This item is designed solely to provide a "hot" trigger wire to activate a relay to power other accessories, such as driving lights, accessory fuse blocks, GPS, or other 12-volt electrical devices when the motorcycle is turned on without upsetting the motorcycle's sensitive CAN-BUS system. This adaptor is also removable without leaving holes in the insulation of the original wiring harness, so it keeps your warranty in place even at the strictest dealers.
