Modding opens the potential of:
-my flashlight burning my pockets
-people who used my light will drop my light due to it being too hot.
-people leave my hot lights on because they didn’t know / too scared to hold a hot light
-inviting more people to turn on the light while pointing at themselves to test power (I still don’t get why people try that every single time)

For personal danger, I couldn’t think of any other than shorting the battery due to my incorrect installation/solder
Usually the dangers are affecting people who used my lights irresponsibly
