Two months ago the indicator relay in LizzyM's CB250 failed. As there were no bike shops open by the time we finished the ride I trundled down to StupidCheap Autos to see if they had anything which might work. They only had one unit at the time with the correct number of terminals (two) so we bought it with the idea of taking it back if it didn't work. But when we plugged it in and all was good. Two months later the relay has failed. I headed back down to StupidCheap and this time found they had several relays all of which look the same but which have different part numbers, which seems to indicate they may be different and not interchangeable. So my question is, are there differences in relays and if so is this is why the relay failed, or was it just bad luck and we got a dodgy one? I had assumed they were in essence the same and that any would do and I could save about 2/3 the cost of a Honda one. But if this isn't the case I am probably better off going with the official Honda version rather than risking replacing a relay every couple of months.
