If you need to, you can quick un clip the battery cover box thingy to get a bit more wriggle room. Put a towel or cloth under where you are working so if the spring clip thingy flies off, it shouldn't , you can find it again. Last time I did a bulb it was a 5 minute job plus 1 hour to find the bleep thing.
