Question about this product?

We're happy to help.

Introducing the re-designed SMART Triple Play®-now sleeker and more compact, engineered to fit seamlessly under your seat without sacrificing any of the advanced technology you expect. This innovative plug-and-play module instantly upgrades your 2025-2026 Softail’s rear turn signals (on models with a center taillight), converting them to function as running lights, full-power brake lights, and turn signals. Choose from 10 user-selectable built-in brake light strobe and flash patterns-or select a steady brake display if desired. Tailor your lighting profile further with adjustable running light intensities, allowing you to precisely match your turn signals' brightness to your center taillight for a unified custom look. Unique programming allows the strobe and flash patterns to activate on the center taillight only, rear turns only, or both, for the ultimate in personalization and visibility.

Our signature SMART function ensures safety and compliance allowing the standard turn signal flash to override brake flashing when signaling and braking simultaneously. For DOT compliance, rear turn signals must be converted to red; compatible with ProBEAM® Red Rear Turn Signals (sold separately) or with stock bulbs and red lens covers. Installation is a breeze using your bike’s OEM P&A port, and if you’re running multiple accessories, simply add our Custom Dynamics® Dual Accessory Cable (sold separately) for hassle-free connectivity.

Easy to install and works great. This is the third one I have purchased, anything that will brighten up and bring attention to me stopping can't go wrong. Also love the option being able to control how bright you to make the lights. Of course, I set mine to the highest brightness

This is one of the most do upgrade you should make to your motorcycle. The difference is night and day. The only problem is that the instructions are very vague, had to go online to follow instructions. Highly recommend anyone with a short tail to do this upgrade.
