found the answer from my local Daewoo dealer- you need to remove the front grill to accress the light assembly- sounds harder than it is - just 4 bolts then unclip the grill each side of the wing ( held in by plastic bolt retainers) prise these loose with a small flat edged driver and pull. The bottem edge also just pulls out from two clip guides.
Bulb replacement is then an easy twist assembly and a standard bulb.
