Well after a lot of placid effort, okay much cursing and box kicking, eventually got three bulbs fitted - two main and one dip. They were very tight to twist out and even more of a trial to get back in, such a shame Skoda could not make them as easy to change as the rear lamp bulbs. The off-side one defeated me, with the fuel filter in the way just could not get an adequate grip on this also tightly secured bulb. At least I can now see the kerb or verge, what might be in the middle of the road not such an issue. Thanks to all for helpful suggestions, pliers did help to get them out. Oh for future reference get an illuminated inspection mirror on a telescopic rod ( think old style radio aerial ) - it really helps !
