I used to take things apart to see how they work but in the process I break them and they never work again I can know something works but understand it's not necessary to know how it works and if it works it's not wise to overwork it because the results can be overwhelming when it fails to oporate as it should turn on the light and turn off the light do not switch the light on and off blinking light draws too much attention not to mention I might break the light and the light might not ever come on again and I'll be back stumbling in the dark attempting to repair it the longer I live the more lessons to learn like if it's already sufficient don't go trying to fix it
