Changing side lights

The side light on the passenger side has blown!!!!! On the drivers side it looks fairly accecable but on the passenger side I can't even get my fingers in. Without reading all the threads (I'm on my phone) can I remove some of the battery casing to get to the back of the passenger headlight or is the some other method that doesn't involve taking the bumper off?

Stupid design!!!!!!

Thanks
 
Take the air hose noise duct thing (having a mental block) off. That's thing to the right off the battery. Just undoes with a 10mm socket iirc...few nuts.

Gives lots more hand space but still a bit of a squeeze.
 
Sidelight can be done by just removing the battery box covers. You can then get in to change it (or at least I can)
