I was in Tesco today actually and picked up a single front mini LED light for £2.66. Was pleasantly surprised as it is very bright. I got it for the hybrid as my main lights are on my Dawes, but considering getting another one for the Dawes to have it in flashing mode (my main lights don't have a flashing mode). The batteries were flat on mine though, but I have borrowed the ones out of the electronic kitchen scales

.
Got a mini pump with gauge for £4.62. It does both Presta and Schrader valves. It is ok, but gets extremely difficult to pump up road tyres. More suited to MTB pressures really. Would get you home I suppose.
Also got some bar ends for £1.33. Don't bother they don't fit on my hybrid handlebars which are a standard size. They'll be going back I think!
EDIT = Ignore the above, I didn't realise you had to take the grips off first (duh!) - Done this and for £1.33 these bar ends are a bargain. They even come with some handle bar caps - they aren't brilliant caps, but they do the job.
