I can recommend the Spanninga Pixeo, less than £15 and "looks like a motorbike from behind" according to my sister. Comes with generous amount of lead and plugged straight into the back of my B&M front light.

I have thinned down plenty of spanners with a bench grinder for various jobs such as this where access is tight - spanners can often be bought for pennies at boot sales.
