Well, although I was born in the south of the Netherlands (Boxtel), I left it when I was six. But I have never before heard a "lont" (wick) being referred to as a "wiek"...
The "VanDale" Dutch online dictionary, doesn't give this meaning either. So although it may well be valid dialect, it hasn't made it to "official" Dutch ;)
I do get hits for wiek / lont in Google though, referring to "wiek" as in the sense of "wick"
Still, I think what we need is a definitive answer from a native English speaker...
