I already knew there were black 510s with Purple LED (Hence me saying as a last resort I could use the battery with an adapter.) but thank you anyway.
I wanted to go with a K8 because of their size, their cartomizers, and the fact that there are readily available manual as well as automatic batteries. With the 510 I've only really seen manuals and had a hard time finding automatic batteries, and from what I've heard the automatic batteries can be temperamental and unreliable.
By the way this wouldn't be my first e cig, though some may argue it might as well be since I'm using Blu's I like them a lot despite so many bad reviews and disapproval, don't get me wrong. I'm just ready to try bigger and better things, and I get the feeling once I get a new e cig, it will leave my Blu pack relegated to a forgotten corner of a cluttered drawer, which is why I want to be able to have automatic as well as manual batteries.
So... back to original question, anyone know how to change LEDs?
