The stock tail and brake lights
on K bikes are rather anemic. Over the years I've done
numerous LED upgrades and this is my latest and greatest.
Since it's just add-on lighting nothing special has to be
done to accommodate the LEDs.
This DIY project takes some
wiring and drilling but the end results are well worth it if
you're up to the task.
"Eagle Eye" LEDs:
These only cost $0.99 each on eBay. The video above doesn't
do them justice but trust me in real life they are
incredibly bright and noticeable, even in bright sunlight.
(They come in several colors so be sure to buy
red ones for this
GS-100A Strobe Controller:
This can be found on eBay for about $2. The controller
flashes the LEDs a few times when the brake light first goes
on and then remains solid as long as the brake light stays
You'll also need a way to tap
into the existing brake and tail light wiring. Piggyback connectors
work well for this.
Notes on implementation:
One minor drawback of using these
LEDs is that the threaded part is 10mm in diameter so you
need to use a drill to enlarge the holes where you install
I put the running light LEDs
through the holes where the rear fender extender attaches.
There are already holes there and it keeps them spaced out
away from the brake LEDs so those stand out a bit more when
the brakes are applied.
I put the brake light LEDs in the
upper license plate holes to have them as high and
(Although for some
reason the Eagle Eye LEDs are sold as 9 watts each, in
reality they only pull about 1/2 watt each so the power load
of them is negligible.)
