Hi (from the u.k!),
It's really easy to replace the bulbs.
The Amigo is the same as as the vauxhall/Opel Frontera in the u.k.
Undo the 2 screws that hold the bonnet (hood?) release and another screw next to the center console that fixes the lower trim panel beneath the steering column.
Remove the panel and remove the connectors from any switches that might be there.
I think (this is from memory) you will see some screws that hold the instrument panel cover - remove them.
Give the panel a good tug (it will come off!)
You will then see 4 screws, one at each corner of the instrument console, remove those and ease the console forward slightly.
Disconnect the electrical connectors to the console (push fit but they may have a clip that you need to press).
The whole instrument console will then come out and you can replace the twistlock bulbs.
You might want to take out the instrument console fuse before you start this - just in case.
Refitting is just a reverse of the above
It takes around 20 minutes to half an hour to do, although I can now do it in around 10! - Hope this helps
Best Regards
Paul
Tip! .. Replace the bulbs with Superwhite LED's (Ebay) - you'll likely as not never have to replace them!
