Light On Digital watch reality check

I understand that people have been saying that Light switches do not work in dreams. I think everyone has there own way of doing reality checks, so i thought i would share mine. I have a Light on my digital watch. When ever I press the button on my watch, it activates the light which brightens the time. My plan is if this Light does not actually light up in the dream then i know I am dreaming. I have been trying this for a couple of days now so hopefully it will work! I have also thought of other ways like telling my mind that if the lights shows any color other than green, then I infact know that i am dreaming. IDK I just like to think of other ways to work with reality checks, because we try to do what works best for us.

who knows maybe others will use this technique:) or its been thought of already!

Sounds like a good RC. Just be aware, that technology RCs may sometimes fail = give you false positive (if they work in your dream, you will think you not dreaming). So it's good to practice more than just one RC, 2-3 are the best. Happy dreams:)
