I have been doing this with my chinese,its fun to watch her, i had topaint the bulb cos of its strange size but lickily its energy saving so they dont het hot, she dosnt mind it, she has been out more since her temp wheel went in. if people want to try it 1st before buying expensive bulbs some tesco's sell cheep back lights for bikes, just so yousee the effect before you buy
its fun i recomend it
