The distance of a lifetime click for an article that might just save your life! Summary: Light Emitting Diodes (LEDs) illuminate 200 milliseconds faster than incandescent bulbs. For a motor vehicle this means a faster braking distance response time, about a full car length of extra stopping distance at 65 MPH.
Don't be deceived by its looks. It may be a bit homely but this ugly duckling is a superstar. The exclusive Happy Trails WOW LED Taillight System transforms your KLR650 to the safest bike on the block. It is routinely blinding: during testing staff members grew accustomed to being temporarily blinded (like looking at a camera flash). We kid you not! Both lights are brilliant, both the taillight and the brake light are exponentially improved to a startling degree. The light installs in seconds: unscrew the stock bulb screw in the adapter unit; the board mounts securely underneath the taillight lens cover. The WOW LED taillight system uses less power, is far brighter (both tail and brake), and is rated to last over 100,000 hours with no signal degradation.
Fitment: fits all Kawasaki KLR650 (A or E series); customers report it also works in the KLX250s.
Power usage comparison (14VDC engine running): Taillight: Stock 1157: 5 Watts vs WOW LED GEN II: 0.1 Amps/1.4 Watts 10 Candela taillight
Brake Light: Stock 1157: 21 Watts vs WOW LED GEN II: .7 Amps/10 Watts 100 Candela brake light (Light brightness testing carried out using a Minolta T-10 light meter at 1 foot).
Flash Pattern: The brake light comes with a built-in dip switch toggle to activate a 1.5-2 second (4 flash) alert flashing before a brilliant steady brake beam or a brilliant steady beam (without flashes).
Notes: Full brightness is not realized unless the bike is running and producing the full normal 14V. To disable the flashing mode slide both switches to the "off" position (switches are tiny toggles on the circuit board.) If your installation causes a small gap between the tail-light lens and gasket, remove a small amount ( about 1/16") of material from the taillight mounting posts with a small file or rotary tool. This will let the lens seal tight and keep water out. The brake light circuit on the WOW taillight requires an active and working taillight to function. Consequently, if you have a headlight cut-off switch that also eliminates the taillight the brake light will not work. Also, the WOW taillight cannot be bench-tested. It must be installed so that both the tail and brake light circuits are active.
Dimensions: The light is about 1 1/4" deep, from the top of the mounting posts to the back side of the circuit board. The circuit board is 1 5/8" wide, and 2 5/8" wide. The maximum width on the installation holes is 3 1/4 while the minimum width is 2 7/8".

I installed the LED tail light I just received onto my KLR 650 and it worked great for one ride. After I got home from about a 45 minute ride I noticed the tail light no longer worked. The LED unit was very dim and no longer blinked. I tested my bike by reinstalling my stock bulb and it worked fine, which leads me to believe something is wrong with the LED unit. How can I go about exchanging it for a replacement?
The bike must be running for the LED to be at the bright function. Please recheck with the bike running and let me know the status.
Will this LED tail light module work with the "GearBrake" Smart Brake Light Module?
If the Gear Brake activates a standard bulb it will activate the LED.
