My sincere apologies icecreamslick, I scanned the thread from the bottom up and mistook your pickys as the same as you posted last time! OK I agree it does look like 2 pin 2mm plug. I think I've got all the bits in the loft, If you want I'll knock a lead up, see if it fits OK in by cannon, if so forward it to you? The down side is the 3mm Leds aren't as powerful as 5mm ones. But I think that what you have got is a slightly older generation, so it may well all balance out. Provided the LED is close to the end of the barrel there should be no issue with how wide an angle it works over.

Yours Simon M.
