Choose Your Lens

  • Red Lens (CD-SBTL-23-R): Classic red lens for a bold look day or night.
  • Smoked Lens (CD-SBTL-23-S): Blacked-out lens that blends into the bike when off and glows red when lit.

Features

  • Dual function: Six high-intensity dual-mode red LEDs work as an auxiliary running light and brake light
  • Seat bolt position: Mounted at the seat bolt, so the light stays visible even when the front end comes up under hard acceleration
  • Aggressive styling: Gloss black housing with a performance, race-inspired look
  • Plug-and-play harness: No cutting or splicing, with a connection that lets the seat come off without rewiring
  • Gloss black bolt: 12-point, corrosion-resistant mounting bolt included
  • 12V DC operation
  • Lifetime warranty on Custom Dynamics LEDs

Kit Includes

  • Seat bolt mounted LED running & brake light
  • 12-point gloss black mounting bolt
  • Plug-and-play wire harness

Note: The OEM Tour-Pak® should be removed for the light to be visible.

Great for: Bagger riders who want extra rear visibility in traffic, at night and in bad weather, with a light that looks like it belongs on the bike.
