The resistors R1 and R2 determine the final charging volt­age and R charge of the battery throught the regulator.
The resistor RL limits the reverse currents through ther regulator (which should be 100 mA max) when the bat­tery is accidentally reverse connected. If R with a bulb of 12 V/50 mA rating this will indicate incor­rect connection.
