There are many flashlights of this type to throw away. Its shell is still usable, just outdated technology. I found this searchlight from Japan recycle shop for $3. I bought battery, reflector, power switch from China online store. This video is just concept of modify existing rather that buy new one.
I hope you find this video useful and enjoy it!
Furthermore, I am happy to receive feedback, suggestions to improve myself.
Thank you very much for choosing to watch my video!
Have a nice day
