Not sure which model I use, though it is perhaps this one, and it does
have a pretty bright blue light. I think of it as a night light.
What I have done in the past with lights that bother me is paint over
it with nail polish, a dark red or any dark color will usually block
it out. If that doesn't work, there is always black electrical tape or
gaffer's tape or such. There is always a way to block the light if you
put your mind to it. On my clock radio I simply put a wash rag over it
at night.
