Right ive got a vespa et4 125 and im having some problems with the indicators. They will not always flash when i press the button left or right. Sometimes they will but its a bit rare/ ive got to press hard on the button. All bulbs are fine and its due for an MOT soon. Any ideas?
Switch or could be a dodgy connection on the bulbs. Quite a common thing. Both the connectors from the wires to the bulb holders and the metal bit that connects to the back of the bulb has a crap connection too.
