Flashlight change mode, switch, press, change a mode! If it doesn't change, you can try to turn on the light, spin your tail, and then turn it on again to see if it changes mode! If it's possible, it's your flashlight switch or a hole somewhere. It doesn't really power off, so it doesn't change mode!
Sometimes the torch does not turn off. It may be that the paper in the switch is broken and should be replaced with paper. If so, the repairs can not be stopped. It is possible that the I mirror and the bulb seat are in contact with each other. R, just leave them apart.
After the process, if it still doesn't work, you have to be careful to open the cover, look inside and copper contact place is rusty; look at the lamp cover against the batteries in place if there is no rust, rust, removing the rust, the torch will be bright.
When the flashlight is not shining, remove the lamp holder and check the lamp holder and cylinder. If there is no problem with the bulb, it may be that the copper in the switch is rusted. Take a pair of scissors and insert into the two small eyes of the front cover. Remove the front cover and scrape away the rust on the copper sheet with a knife.
