Custom Dynamics GEN-4-R-25ST Genesis 4 Solid Red LED Rear Turn Signals for 2025 Softail

The Custom Dynamics Genesis® 4 GEN-4-R-25ST are solid red LED rear turn signal inserts purpose-built for 2025 Harley-Davidson Softail models. Engineered as a direct plug-and-play upgrade, these inserts utilize JAE connectors to mate perfectly with the factory wiring harness — no splicing, cutting, or modifications required.

Key Features:

• 48 Super-Bright Red LEDs per unit delivering greater brightness and a wider viewing angle than previous Genesis® generation inserts
• Dual-Intensity Function: On models without a center taillight, all 48 red LEDs operate as a dim running light and switch to full-intensity illumination when the brake is activated
• Turn Signal Only Mode: On models equipped with a center taillight, the solid red LEDs flash as a dedicated turn signal
• JAE Connector: True plug-and-play installation designed specifically for 2025+ Harley-Davidson Softail wiring architecture
• Traditional LED Cluster Design: High-quality components for superior brightness and long-term reliability
• Sold as a Pair

Important Notes:

• A Custom Dynamics® red, smoked, or clear ProBEAM® motorcycle turn signal lens (sold separately) is required for DOT-compliant installation — OEM lenses are not compatible
• Compatible with the Custom Dynamics® SMART Triple Play® run/brake/turn controller (sold separately) for additional lighting functions and brake strobe patterns

The Genesis® 4 rear turn signal inserts are a straightforward, high-visibility upgrade that brings modern LED performance to your 2025 Softail while maintaining factory-level integration.
