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 ProBEAM® Red Rear 1156 Turn Signals or Genesis® 4 Red 1156 LED Turn Signals (sold separately) or with stock bulbs and red lens covers.
Add the SMART Triple Play® Extension Harness to use up to three Custom Dynamics® dual intensity lighting products as run, brake, turn (sold separately).

Removed the tri bar aka mullet from my street glide, this in conjunction with a couple other bolts made it possible. Thanks for all the help along the way, super friendly staff, made ordering super easy.
Great product! Works extremely well.
Very easy installation.
Super easy install and works perfectly to light up everything in the rear of my road king and make me more visible on the road.
Love it! I had an issue at first with the LED aftermarket brake light that I had. I bought another one and it works just fine now. Bike is definitely more visible. Highly recommend.
Pretty quick ship works as expected this is the second purchase of this item ,being able to turn down the run lights to match the tail light is a must for me works great
New box worked great. Default out of box settings were just right. Running lights nice brightness. Braking brightness just right. The three flash pattern is a bonus. Was able to find a spot for the new smaller box under the seat without too much trouble. Very happy.
Worked perfectly, on my 1999 Sportster had to set special configuration as I am using a 3 wire turn signal which has dedicated DRL, after calling support they guided me thru it and now I’m one happy camper! Brake turn and DRL all work flawlessly
Very easy install and works as it was described!
I had been wanting to add more visibility to my Fat Boy by using the rear turn signals as brake lights, so this unit was the perfect answer. Took minutes to install and program and the results were better than expected! Plus, Custom Dynamics got this to me super fast without additional cost.
The Triple play was exactly what I was looking for in features and plug and play convenience. Easy install and set up and with so many options on the brake light sequence its hard to pick one. Also the icing on the cake is the ability to choose if you want your turn signals to be used as brake light and sequence them with the brake light. you absolutely cannot go wrong with this module. Do not purchase a knock off you will be disappointed. Shipping was lightening fast and I have Zero complaints. Great product, great service, great company.
A must have ! Can’t be to safe on the road!!!
I love the triple play unit. I think it's great to set flash modes for rear break and turn signal lights. It make you more noticeable and its a great safety feature. Plug and play, but take your time reading the instructions and follow them closely. The instructions are well written and easy to understand, just don't rush through it. I think the triple play is a must have feature.
Works just as demonstrated. SMOKIN!
