Ninja 250 Brake light upgrade

So I wanted o upgrade my tail light so that inattentive drivers know I'm slowing down. The biggest problem I noticed on the Ninja 250 is that the standard light (single pod) doesn't have good contrast. Even though the bulb is powerful, I don't feel it suits safety very well.

It was dumb luck that I discovered a perfect MR16 LED bulb on Amazon for $13.

It's a 5W, 250lm bulb which after removing some plastic, it fits perfectly in the extra unused pods on the tail light.

Originally I was planning on having a dimmed light because the controller inside the bulb supports some dimming. Turned out I would have needed to develop more than what I wanted to. The single LED driver wouldn't have been able to power 6 LEDs (from 2 bulbs) on the 12V bike power.
You can see the 2 MR16 bulbs on the external pods. They fit (with removed lenses and rings) right where a bulb socket would have gone. 

I decided to just have it completely off and then on when braking only.
Normal operation just has the standard running light.
With the brakes on it's a LOT better than just the center bulb only. The 2 pictures are taken a the same speed/aperture for good comparison.

Overall I'm very happy with the upgrade and feel a bit safer. The LEDs turn on almost .25s (or more) faster than the standard bulb. The LEDs also allow me to brake flash better to warn people following too close or just when I may be stopping/slowing "unexpectedly"
