Stall modification - lights

Here are some lights I purchased today for my stall. They are 50 LED pack of solar lights that turn on automatically when the sun goes down, after charging. I got them for £4 - they were reduced for some reason, but they work perfectly fine. I am also looking to get some form of small lamp to go on either the front or back of my cart so that I have something to light it up a little more if I am pulling it along in the dark.

Nice solar lights
