You can get perfectly decent lights for a couple quid.
Poundland even does decent lights for £1 a pair. They are the same kind that used to cost about £6 on ebay a few years back. I used a set for ages, they were fine but the batteries died a little quicker than quality lights and they were slightly less robust. But still good.
Well times have changed since I last bought cheap lights.
