my flashlight had a broken switch and a cracked bulb. so, i opened it up.
Step 2: Get the LED
i used a single blue LED. It won't be that bright, but it was the only thing i had. I also used a 2-hole connecter for the LED. I also added a bulb head so it looked like a bulb.after that, I rigged the LED on the reflector dish.
Step 3: The Switch
the original switch was broken, so i used a button switch. i used a hot glue gun to put a hole, and fit the switch inside.
Step 4: The eletronics
get some batteries. i used 2 AAA batteries and connected them to the switch and the LED.
Step 5: Reassembling
After that, reassemble the flashlight and It's done!
