same with mine ... after 5 from motorshop, the battery died, the
horn dead, the sign bulb stop blinking. Then I recharge the
battery, after 1 month .. the bulb stop blinking again.. I think it
is because of the front beam. Original bike from factory can switch
off the front beam completely, but for bikes in SG, the dealer seal
up the switch with glue (it is very obvious on SP's handlebar, got
glue there).
In other countries, front beam only used from 6:00pm - 6.00am, or
when foggy/heavy rain on daylight...
