DENALI 194 Marker Bulb Plug-and-Play Trigger Wire Adapter (Fits Some BMW, Ducati, Triumph And Other Motorcycles)
Upgrade your motorcycle’s wiring with the DENALI 194 Marker Bulb Plug-and-Play Trigger Wire Adapter (SKU EC.02350). Designed to work with vehicles that use a 194 marker bulb (often used as a day-time running light) and have a CAN-bus or sensitive electrical system, this adapter provides a clean, safe, and reliable switched power source for accessories like driving lights, fuse blocks, or other 12 V accessories.
Key Features
- Recognises the 194 marker bulb socket and repurposes it to provide a switched 12 V trigger lead without altering factory wiring.
- Built-in reverse polarity protection, ensuring safe insertion and operation.
- Plug-and-play design: no cutting, tapping or modifications to the factory harness required.
- Ideal for motorcycles with CAN-bus systems (especially late-model BMW, Ducati, Triumph) that use 194 marker bulbs.
Benefits
- Clean and Safe Wiring Integration: Maintains factory wiring integrity and avoids potential error codes or CAN-bus faults.
- Dedicated Trigger Lead: Provides a reliable switched power source for accessories like driving lights, auxiliary gear, or fuse blocks — enabling smarter installs.
- Minimal Tools or Expertise Required: Straightforward installation keeps your time in the garage low and your ride time high.
- Preserves Warranty & Resale Value: Since no permanent wiring cuts are done, easier to revert back if needed and retains factory-like appearance.
Installation Overview
- Remove the existing 194 bulb socket from the headlight housing.
- Unplug the bulb from the socket and insert the DENALI adapter board in its place.
- Use heat-shrink tubing to secure the socket and board.
- Reinstall the bulb, then utilise the new lead provided to run to your accessory relay or fused harness.
