Overly sensitive clicky button on light

I bought one of these from Dinodirect
MTE SSC P7-C 5-Mode 900-Lumen LED Flashlight


I use the light on my mountain bike, but the mode tends to switch when ever I hit a bump. Is the switch something that can be opened and fixed/mod to be more shock resistant?

Sounds like the rubber cover is pushing against the switch, keeping it partially depressed. You want to have a little play in between the rubber cover and the switch. You can take it apart and trim the little nub of the back of the rubber switch cover.
