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 motorcycle’s rear 1156 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 with ProBEAM® Red Rear 1156 Turn Signals or Genesis® 4 Red 1156 LED 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.

This was a SUPER easy install with a huge impact on visibility on my lowrider s . The rear signals are now running lights and brake lights. With the strobe effect on brakes I’ve noticed people stopping a little further back

Easy to install and program to desired setting. I have to mention, Custom Dynamics has impeccable customer service.

Great so far - installed Friday and went on weekend overnight ride next day. Had a little issue upon setup but tech quickly resolved for me over the phone! Part arrived fast and I thought it was a fair price.

Love how this product works. The installation instructions could have been a bit clearer:
1) B&W photos don't provide much value. Perhaps a color copy could be made available on your website?
2) On step #3, the instructions were clear on connecting the left and right turn signal connections, but did not mention the connection for rear brake light. While very obvious, a simple sentance about this connection would be helpful.
3) Removing the wire connection above the P&A connector made things easier, as I could them remove the P&A connector from the bracket to plug in the Triple Play. Remounting the connections to the bracket might seem obvious, but could be mentioned in the instructions.

Had to tun through the programming the turn signal intensity a couple of time, but finally got it. I now need to upgrade my bulbs to LEDs to really show off this product.

Fairly Easy and Works Great

Installation was fairly easy but more involved than my other bikes, thank Harley for that. Had to contact CD to get my blinkers to act as running lights but, as always, they were quick to respond and we had them working in no time. CD has never disappointed!!
