Which allowed me to see the spring around the pill.
And tadpolPilot for suggesting to tight the spring around the pill.
Okay, me and my all thumbs, went took the light apart, the bottom of the spring, I squeezed it until it was a tight fit on the pill. Didn't do this before, the spring was hanging loose all the time.
Anway, with the spring tight around the pill, I put it all back together. The light came on, and then I held it in my hand and shook it hard! No mode changes. With the light in my hand, I bang it on my leg about 10 times. (hurt too), as to simulate rough riding on the bike, NO MODE CHANGES. Going to put it on bike tonight, and ride over the roughest ground I can find, if no mode changes, and no more on one day, and off the next, this light is a KEEPER..
Here are pics of the SUGGESTED FIX!!
Here I am picking up the pill by the spring and the pill is staying attached to the spring, this was never like this before..
As in this picture, the spring is not moving around,
Right now, you all should see the smile on this 72 year old kid!! Can't wait until nighttime to try this out. I am almost sure this is going to work.
One more thing, not trying to plug Tmart, but they have been SUPPORTIVE from day one on this. No return shipping, and at every instance, I get an apology, and and offer for a refund, with a return label. IMO, if the other companies were just 1/10 as good with their customer service, it would be super good in Flashlight World.
I am going to say BIG THANKS TO ALL, you guys/gals are GREAT/SUPER/AWESOME!!
