I bought a Led clock that glows bright red.  Large numbers 3 inches high.
Wonderful!  You can see it from a mile away but in my bedroom at night it
turns the bed coverings a sea of red.   I crawled out of bed and turned the
clock around only to discover, that did not work either.  I solved the problem
with black netting from Hobby Lobby's fabric shop.  Always think things out
before you buy or you will be crushing netting to cover your mistakes. 
Comments are welcome good or bad  have a great evening and remember
