What's inside a Wilko solar security light?

nice simple fix,

Those wires are often made from horrible materials with hard plastic insulation, same crap as the 9 Volt battery clip terminals. Bit of corrosion on the pads.

Yeah, that seems about right, 9 volt battery snaps tend to be "corrode and snap" too. I was tempted to change the wires (I've still got a few reels of 10/0.1mm² as I used to use quite a bit of it) but ended up leaving them as they were and just resoldering all the ends.
