Anti-theft Protection


With the light screen is on, simultaneously press and hold the “+” and “-“ switches for 1s to turn on the anti-theft alarm. A distinct “DI” means the function is activated successfully. 



  1. When turning on/off the anti-theft alarm, make sure the security key is inserted in the remote pressure switch and the remote pressure switch is connected with the bicycle light, otherwise the alarm will not be activated/deactivated.
  2. Turn off the anti-theft alarm before unplugging the remote pressure switch to avoid accidental activation of the alarm. If the alarm is accidentally activated, plug in the remote pressure switch to turn off the alarm.


  1. With the anti-theft alarm turned on, 3s after the security key is removed the bicycle light will enter anti-theft status, and any movement of the bicycle light will activate the alarm (100-110db). Plug in the security key to deactivate the alarm; the bicycle light will exit the anti-theft protection automatically.

Note: If the security key is lost, turn on the bicycle light and simultaneously press and hold the “+” and “-“ switches over 15s. In case of loss of the security key, contact the manufacturer to obtain a new key.


Intelligent Memory Circuit

The light memorizes the last selected brightness level on General mode. When turned on again the previously used brightness level will be recalled.


Low-voltage Warning

When the voltage level drops below a preset level, the bicycle light is programmed to step down to a lower brightness level until Low output is reached. The functional switch will flash red when the runtime of Low output level is less than 10 minutes.


Overheat Protection

The light will accumulate a lot of heat when working on Turbo mode. The light will automatically step down to a lower brightness level to reduce the temperature, but turbo mode can be reselected.

I bought the bc35r by evaluating the comments here thanks everyone

Thomas Spellman

A little heavy for a helmet setup, but overall good coverage, and versatility, I give it a definite thumbs up!

Gavin Donnelly

Bought it for my son who is a Marine stationed in Okinawa. He said "it's bright as f@!k".


This is my favorite light for mountain biking. This has the widest beam of any of the bike lights I've used. The neutral white allows better depth perception while riding in the woods. The display with time remaining is a nice touch so I know I've got enough light to make it back to the car.

My one complaint is that after riding a decent amount the mount starts to loosen a bit side to side and there's no way to tighten it up. It the top rail of the mount was held to the band with a screw that could be tightened, I think it would be better (or at least some way to lock it down). I didn't notice this as an issue until this year; I used it all last winter on a few rides a month.


It' great headllamp, i can see ahead much better compare to others
