TST LED Front Flushmount Turn Signals for Suzuki GSX-S1000F / GSXR 600 750 1000

Retaining nut is not sufficient, as the other user, I modified the original mount plates to suit. Signals were clearly not designed for this bike, I knew that going in though, and when mounted, it's not obvious unless you know to look for it. Aesthetically, they're great. Functionally, I'm a little concerned. They are barely visible at all in direct sunlight, possibly because that do not have a diffusive cover or maybe the simply aren't bright enough, the result is that they do not function as turn signals unless you are in the shade or driving at night. The Suzuki wiring harness worked great, and the new relay is working perfectly.

Advantages: They look good.

Disadvantages: Installation, day time operation.

So most of TST's products are spot on and their videos are always super helpful. But this product just missed then mark. Fitment was subpar, and you can even see it in the video. The nut and the turn signals should have simply been larger.

HOWEVER, you can easily make this work with a slight mod. Take the OEM signal spacer, use something like a hacksaw or coping saw to cut the little nib off it to make it flat - sand if necessary. Then take a drill bit the size of the larger hole in that spacer and drill between the 2 holes. Use a file to smooth the new large slot out. This spacer will go in-between the signal and the nut. You can now tighten it to your heart's content (within reason, finger tight is fine) and will have zero issues with it popping through the opening.

Advantages: Appearance. It looks sleeker, as expected from a cosmetic mod.

Disadvantages: Not technically road legal? But I mean, they don't claim to be, so what do you expect. Nobody will care though.
