http://www.ebay.co.uk/itm/111458583832 They work out slightly smaller in length than currently installed (just bend the contact terminals closer-- job done)

Removed prop, installed blanking plate on IRD, changed every fuse and every relay in engine compartment, replaced temp sensor, changed 4 wheels, replaced interior bulbs for LED, replaced busted rear ashtray (i just wanted to have everything looking nice), changed battery. fitted new clutch...

I'm new here. But i just replaced my "239" festoon bulbs (front and rear center) with a 6 led version and i'm really happy with them. At night they're bright and clear. I personally wouldn't change them again. Led bulbs don;t require any modification to fuses. Haven't changed the L/R reading...
