The blue light is the one that gave me away in the Amazon Rainforest. It is also like my good pall The Doctor's T.A.R.D.I.S. , it's bigger on the inside than on the outside!
I think my discreet landing has failed. Apparently I was spotted in the Amazon rainforest. My ship's emergency blue light kept flashing no matter how much I tried to put it off and while I was hiding one of you humans have filmed me with your vidjo camera thingy. I may be in great danger.
Also, I didn't realise you had met my cousins from Mars.
I'm guessing my family has never had much luck with being secretive.
