- 1x Left Chrome Under Tour-Pak Accent with integrated LED light
- 1x "Y" Wiring Harness
- 2x Alcohol Pads

Installation Steps
- Preparation: Ensure the motorcycle is turned off and the ignition key is removed. Disconnect the negative terminal of the battery to prevent accidental electrical shorts during installation.
- Locate Mounting Area: Identify the area under the Tour-Pak where the accent lights will be installed. Refer to your motorcycle's service manual for specific panel removal instructions if necessary.
- Clean Surface: Use the provided alcohol pads to thoroughly clean the mounting surfaces on the motorcycle. Allow the surface to dry completely. This ensures proper adhesion if adhesive backing is present on the accent pieces.

- Secure Wiring: Use the provided cable ties to neatly route and secure all wiring, preventing it from interfering with moving parts or being exposed to excessive heat or abrasion.
- Test Functionality: Reconnect the motorcycle battery. Turn on the ignition and test the run and turn signal functions to ensure the new LED lights operate correctly.
