Grab the attention of the distracted cager behind you with a brake light modulator. This tiny device emits a series of light pulses whenever the brakes are applied.
I got mine from eBay seller zowwie438 for $21 shipped. Arrived quickly and quality is pretty good.
Here's a step by step guide to installing a brake light modulator on your Ninja 300:
1. Get your modulator, a led bulb, side cutter and needle nose pliers.
2. Open the bike's trunk and locate the brake light harness. Carefully slice the heatshrink tubing open to expose the three wires -- blue, black, and red.
3. Splice the modulator between the blue wires (signal). The single red wire with the yellow label goes towards the led bulb.
4. Black goes with black. Carefully expose the copper wiring and tap the modulator's black wire to the brake light harness.
5. Solder the wires together (optional), get electrical tape, wrap it all up and pat yourself in the back for a job well done!
