TST Universal Brake Light Modulator

Great product overall, I just wish It had more modes to chose from.
I think the flashy one is 9 flashes? Why 9? I want probably 3 to 6. It kinda walks the line between being useful and giving everyone behind me a seizure. I'm like an obnoxious, LED, epilepsy-inducing firefly.

But yeah, super cool

Advantages: flashy boi

Disadvantages: terrorism

Great product, would have given this a five star if it only came with instructions or indication of what was the output side or vice versa of T-harness. I figure it out that the red wire from brake modulator (one of the yellow wires on T-harness) goes to bike harness side and the blue wire from brake modulator (the other yellow wire on the T-harness)
is the output side which goes to taillights.

Advantages: Easy to install as long you find out wires goes to what.

Disadvantages: None, at this time.

Thnde kit and programmed features are great. The modulator works well and has easily programmed settings allowing for flash timing speed, Programmed flash and flash to solid and and standard are all easily changed. Installation is easy with some knowledge of which wires go where and a basic metric set of ALLEN wrenches. (universal kit) Overall the kit performs well and with some brands of motorcycle plug a play kits are available. Suzuki is not one of them, I would like to think yet..... not that it matters now that I have mine hooked up. I give this kit a 5 star rating for overall quality and ease of install. Considering it is the **UNIVERSAL** kit you will have to use your head to get the correct wires in the correct spot. The kit also is easy to hide from view so the its like it is a factory install. Video coming soon. Installed on a 2017 GSXR 1000

Advantages: Quality, Easy to program, and Install. The universal kit will install on any brand of Motorcycle. There is also a plug and play kits for other brands of bike.

Disadvantages: splicing the wires and figuring out the correct wires. The wires on my 2017 Suzuki GSXR 1000, didn't even have the sames color wires on the factory harness at the connection, let alone the universal harness.

I just installed this modulator to my m109r. It was a replacement for a previous modulator from another company. The previous modulator was clumsy to install and awkward to mount, but the TST was night and day better. Easy, intuitive, and adjustable. It could even be easily mounted to be accessible without removing the back fairing, albeit I doubt I would ever need to adjust it anymore. Probably the easiest electrical install I've ever done on my bike. I recommend it as the go to option.

Advantages: Very easy install
Intuitive features
Functional and adjustable

Disadvantages: None, works as intended
