Hi Brian - Thanks for your advice. Vehicle Wiring Products (my electrical supplier of choice) do indeed supply the required flasher unit. I was just about to place an order with VWP when John Ellis, the club two stroke man, offered to supply the same item together with some other Leader parts. In the interest of club funds I have decided to go with the AOMCC - two stroke spares, in this instance, but I really do apprecieate your input Brian. Best regards - Bob Atkinson, Kings Lynn, Member no 6990.
