How to fix a circuit programmed with planned obsolescence to malfuncti
I bought (2) headlamps at the end of April 2016. On December 20th, 2017, my headlamp began flashing erratically & could only be turned off by removing both batteries. I immediately put fresh batteries into my other headlamp & it began blinking erratically like the previous headlamp. Again, the only change that I could make in the light's pattern of blinking was to remove both batteries thereby turning off the light completely. No damage is visible on either headlamp. After only 1.5 years of nightly use of either one headlamp or the other headlamp purchased together, both preform erratically without wear being at fault.
Is this a good question?
