Can't believe I never did this earlier. It's such an easy job done in like 30seconds.
First pic is a comparo with the single light on top and the 3 light ghia one on bottom.
The light just pops out. There is a little metal clip in the middle of the front side of the light that holds it in (faces the bonnet). I just slid a little flat head screw driver in there and it uncliped by pulling the whole light down.
The hole thats left after the light in poped out and both plugs are undone.
Also if you want to take the aerial off the roof just undo that silver part you can see in the middle.
New light plugged in. The connections are all the same as the single light.
Just test the light at this stage to make sure it all work.
The end product in.
Standard interior light on.
Both maps lights on.
It has the std 3 way switch plus 2 push buttons for the map lights. Cost might put some of you guys off I payed $143.87. Part # - 3S7A13K767AA
