The BK20-AB conversion kit includes a rechargeable battery pack, charger and remote control switch. The kit connects with the head of your XT20 flashlight to create an ultra-bright, far-throwing bike light with long run-times. Designed for the rugged trail, the BK20-AB kit is durable, secure, shockproof, waterproof, easy to operate and quick to detach from your bike.
Please note that the XT20 is NOT included. The BK20-AB kit contains the parts to convert an XT20 into a BK20 bike light.
With two heads and a maximum output of 1200 lumens, the XT20 makes one of the most powerful and desirable bike lights in the world. The remote switch can be attached to your handlebar grip for full remote control of the BK20. Then, when you need a flashlight, you can attach the XT20 head to its original body tube – making it a multipurpose light for exploration, hunting, camping and travel.

Switch and Operations
Momentary activation: Click anywhere (except strobe switch/circular button) on the pressure pad to active momentary-on mode.
Constant-on: Press and hold the constant-on switch for more than 1 second for constant-on mode with high output.
High-Mid-Low Outputs: With constant-on activated, press the constant-on switch for more than 0.6 second to cycle through High-Mid-Low modes. Click anywhere on the pressure pad (all but the strobe switch) to turn the light off.
Strobe: When the light is on or off, click the strobe switch (circular button) to access the strobe function. To deactivate strobe, click the strobe switch again--- this will switch to the previous output(s). For example, if it was turned off prior to accessing the strobe function, the unit will return to off mode. If it was set previously to the mid output mode, the unit will return to mid output mode.
 Usage and Maintenance
Do not shine light directly into eyes.
Remove battery when stored for extended periods.
Replace and lubricate O-Rings as needed to maintain IPX-8 rating.
