Custom Dynamics CD-CDSBTL18STS Seat Bolt Mounted Taillight Black for Harley-Davidson Softail 18-Up

Add a bold, race-inspired edge to your 2018-2026 Harley-Davidson® Softail with the new Seat Bolt Mounted LED Running & Brake Light. Designed with an aggressively styled gloss black housing, this compact yet powerful light delivers standout performance and visibility thanks to six high-intensity dual-mode red LEDs. Functioning as both an auxiliary running light and brake light, it enhances your presence on the road for added safety in all riding conditions. Its innovative seat bolt mounting position keeps the light visible even during hard acceleration—making it truly wheelie-proof—while maintaining a clean, integrated look. Installation is quick and hassle-free with the included plug-and-play harness, allowing for easy seat removal without rewiring. Finished off with a durable, corrosion-resistant 12-point gloss black bolt, this upgrade combines form, function, and reliability in one sleek package.
