The buses have been in service for 10 months so are well within the warranty period.The parts are faulty so the light needs replacing. We are only trying to help you by suggesting repairing with new resistor packs. I do not care which solution you choose.It does not matter if FTBCI or BCI or my pet cat chose the parts. Why would you even ask this question? If the part is faulty it must be replaced.Why is such a simple request always turned into an argument?Please arrange replacement parts immediately.
