TST Brake Light Modulator for Select Suzuki OEM Tail Lights
TST Brake Light Modulator for Select Suzuki OEM Tail Lights
4 out of 5. And that is based in initial install. Easy. One star removed for the sealing of the modulator board. No gasket on the lid. So not waterproof as hoped. A screw on top with an o-ring would be ideal. Much more expensive no doubt.
