I was just browsing through pictures when I noticed that an SQ bird had these orangey tip things on the back of the wing strut type things! (I'm sure someone could correct me on the lingo!) I looked around for earlier pictures of the plane and found that they were without these orange tips!
Here's the plane with and without this orange bits!

It'd be much appreciated if someone could tell me...
a)What are these strut parts called?!?!
b)What the orange tip is for??...and why the sudden change!
p.s sorry if its been discussed recently!!
