For help, to burn out problems LED lithium battery 7 headlights 3
light according to the brightness, the appropriate range or small resistance value, maximum resistance to the brightness of satisfaction as the standard to determine the final value of series resistance.
The first series of 1 6 ohms in lithium battery cathode, 1/2 watts resistor, then access lamp circuit,
If you don't know the parameters, you can only rough them.
