When replacing the rearside brake bulb I dropped the wing nut as I was securing it back on. I seemed to have dropped it behind a sealed compartment and can only get my hand in so far thru the open gap. Am I best to just buy a new one and replace it, or is there an easy way to get this just I don’t know what where to look? Thanks in advance 

try getting a magnet in there to get it, failing that just get a new one, you can probably get a new one from your local motor factor or somewhere like B&Q

you need a magnet  the pen shape one 

Aren't the wingnuts plastic?  

Buying another one is probably the easiest option, though it might rattle annoyingly if you can't retrieve the original.

Vacuum Cleaner.

Stick with Blutak on the end.

I have done the same. Gave up and got another from a scrap yard.

Thanks for the replies. The ironic thing is I watched a YouTube video (I’m a female) on how to remove the back rear light and in the video it said specifically “be sure not to drop the wing nut” and well no better person than I to drop it. Needless to say, after 10minutes of trying in vain to get the dropped wing nut I gave up. Phoned two local car stores one of them been Ford, to purchase a replacement yet, it had to be ordered in though will be here for Friday. I posted here just to be sure there wasn’t a simple way to get it. I too initially thought of a magnet yet then remember it was plastic 

Have you a phone with a camera & light on it ? Maybe stick the phone into the gap and see if you can see exactly where it is located, get yourself an all wire coat hanger, unravel it into a length of wire, kink the wire into an L shape, wrap a load of cellotape around the end and go fishing, this is how I retrieved mine.

The blu-tack is a good idea but tried it but the plaggy wingnut kept falling off.

The wingnuts are totally unnecessary and are another example of total over engineering; the 2 x T25 s crews are more than adequate.

Now, that's a first, I've never seen Ford being accused of, 'over engineering' 🤣
