Thanks Ron - the Wiltronics site seems to be the go - no wattage is mentioned but that size bulb will be around the correct wattage. I might buy a few on line to last me for a while.
EDIT - just saw`you second post - more good options thanks - I find it amazing that mainstream specialist auto electric supply companies like Ashdown Ingrams do not sell this stuff - just the same as Super Cheap and Repco - Narva, Hella and maybe Philips.
Cheers
Garry
