<p>There are two reasons that this might happen. First, the light features Intelligent Overheat Protection which may be triggered after a period of use because high-powered LED lights can generate a lot of heat. When the light reaches 140&#xB0;F (60&#xB0;C), the overheat protection will be triggered and the light will step down to a lower output while it reduces temperature. Once the temperature is below that level you will be able to select the output again. Second, the light has a low-voltage warning. When the battery voltage drops below a preset level, the light is programmed to downshift to a lower brightness level until Low is reached. Recharge the battery to restore the higher output levels.</p>

Why does the BC21R V3 sometimes downshift to a lower output level?

The BC21R V3 bike light does not feature a lockout function but you can prevent accidental activation of the light by unscrewing the tail cap a small amount or removing the battery while it is not in use.

<p>If your light won&apos;t turn on or won&apos;t charge, be sure to remove the plastic insulation disc inside the flashlight body as soon as you get the light. Confirm that your batteries are good. Try using the battery in another device. Confirm that the battery/batteries are inserted into the light facing the correct direction. The Positive (+) side should be toward the head (LED) of the flashlight. Confirm that there is only one o-ring on the light. The o-ring that comes in the box is a spare. The light already has an o-ring on it when you first remove it from the box. If you put on the spare o-ring, please remove it as this will prevent the light from making a full connection with the batteries. Lubricate the o-ring using a small amount of silicone grease on the end of a cotton swab. Confirm that the tail cap piece is fully tightened to the body of the light. Click and hold the power switch for .5 seconds. A single click will not turn the light on, you must hold the button down. After you have completed the above troubleshooting steps, if your light is still not working, visit our Warranty and Repair page (https://fenix-store.com/pages/warranty-info) to review the policy and submit a claim.</p>
