[FLASHLIGHTBOY]

on the right side hand brake control .. there is a brake switch there... when you have either the left or right hand brakes applied the rear brake light will come on... it looks like you have no rear brake( as you have brake controller on the left side ) if the tail light works.. then it will come on... safety device.. the front wheel being sticky could be because the front brake cable is tight.. appling the brake ... or the nut is loose... sometimes when you assemble it the brakes are applied abit...the shoes catch the drum and drag.. check it out... it is good that you checked everything over.. make sure the chain is adjusted right... see how to adjust chain in the threads in the ATV section.. have fun
