Step 6: The flashlight is ready, go ride your bike
few things : firstly the maglite is quite thick metal thing that way you dont really need aheat sink. you can use a thermal paste between the maglite ...
Step 5: Making the battery case
Hey, you can buy from the internet ( my case DX) but you can buy it anywhere, you need to lok for holder for two 18650 case
than you need to replace the wires that came with the holder to thicker ones. solder them nicely
remember before soldering the wires you need to put the shrinking tube on the wires until it get to the led it self
then solder the (+) straight to the battery case
the minus solder to your switch ( use what ever you like) then solder it to the battery case.
thats it! if you did all with the instructions you need to get very very bright light.
