I want to change the security light that is red to blue but I'm having a hard time finding blue led's. I've gone to Radio Shack and another huge electrical supplier and they don't carry blue led's. Where can a get them? Is there any place in Toronto that has them?

 

I've always gotten them from Radio Shack, but not every store carries them. Ask to take a look at the big catalog, I know they're in there.

 

check this guy's page out

he has some good stuff on doing led's on the window switches but he has some great links to other led related websites.
