Thanks to the guys who answered my last indicator question - https://netrider.net.au/forums/viewtopic.php?p=324878#324878 - I took the bulb out, and the connections were corroded and the bulb, though not blown, was all white as though burnt. Upon replacing it, it worked. But then a new problem arose. I tested the right bulb by replacing it with the left side bulb, and the the indicators on the right worked fine, flashing properly, whereas the left now mimicked the problem the right had had : back light on, but not flashing (while fron light not on). It seemed the problem was fixed. However... I don't know if I did something bad by doing that test, because now, even with a replaced bulb (and so working bulbs all round), *all* the indicators come on, but they have a problem flashing. Riding along, they either they flash slowly, or not at all (simply remaining 'on'). At idle they might not flash, and will do so once (once only) if I revv the bike. Any opinions on this? Cheers, Matt.
