TST Brake Light Modulator For OEM Honda Grom Tail Light 2013+

The car behind you isn't paying attention. You are — and now your brake light can make sure they do too.

The TST Brake Light Modulator is a simple plug-in upgrade for any Honda Grom (2013 and up) that turns your stock tail light into a genuine heads-up for everyone behind you. No cutting wires. No chasing down an electrician. Just a smarter brake light that works with your existing setup.

You get three modes to choose from: Strobe Alert hits hard and fast when you squeeze the brake — great for snapping distracted drivers out of autopilot. Intermittent Pulsar gives you a rhythmic flash that reads as urgent without being chaotic. Pulsar keeps things a little more subtle while still standing out from a sea of static brake lights.

Key Features

• Three flash modes — Strobe Alert, Intermittent Pulsar, and Pulsar, so you can match the mode to your ride
• Plug-and-play install — works directly with your OEM Honda Grom tail light, no wiring headaches [CONFIRM]
• 2013+ Grom compatible — fits the full modern Grom lineup out of the box
• Demands real attention — a flashing brake light is dramatically harder to miss than a static one
