Without seeing the entire code, I can only guess.  But I'd bet that you're
seeing a reflection of the light
source.   If the current material is fairly reflective, you'd have a good
chance of getting a highly specular
reflection like you describe.   Try changing the position of the light(s),
and see if the result changes.

Just my $0.02 worth...

Good luck!
