Blue Christmas Lights

Does anyone understand them? They may or may not be linked to Hanukkah. They could be said to invoke images of peace and serenity. Some may find them soothing. But I just don't get them, really. And there are loads of them in my neighborhood to contemplate. I'm just a boring white lights girl who occasionally thinks nostalgically to those old skool, opaque multi-colored bulb lights of my childhood I guess. And we still have ghost eye decals from Halloween up on our door, so I probably don't have much room to critique.
