How many different screwdrivers do you need to change car lightbulbs? (Ford Fiesta 2012) Which are the proper ones to use and which ones can you get away with using please?

If they're not TX20 I'd be surprised 

I think they're T30.  They do have a slot going right across so you can just a large flatblade though.  Will also need a small flatblade for popping the plastic grill clip out.

2x T30 screws - as Tom said a very large/fat flatblade would also do it.

Also one of those plastic expanding/locking pins where you have to lift out the central section first.

(spookily I have the headlights out as we speak)

Thanks. I really need to learn as it's embarrasing keep going to halfords and having to ask. It's always the same young girl doing it for me.

I'd be more concerned at the cost charged by Hellfrauds.

Thanks. She is quite hot though, must admit.
