Little warning light came on this morning to tell me that a bulb had blown somewhere
turns out it is the wing mounted indicator one that has pooped.
How do you get to this?
I haven't got a haynes manual (yet)

Mk 1 or 2?

Oops, sorry 51 reg, so I suppose Mk2.

just looked in me haynes andit sais

push the light toback of car slightly then use flat blade screw driver and prise the light off using the blade under the edge towards front, sugests puting a cloth under blade to avoid damage to paint. the light should prise out then you twist of the back to get at the bulb.
