The Memphis mom -- who took a photo of the brake light -- claims witches use a pentagram as their evil symbol and says kids shouldn't be riding on buses with lights shaped like pentagrams.
The woman, whose name is not being released because she's getting death threats for her views, told a local TV station, "Anyone who fears a God, if not God and Jesus Christ, should be outraged.If you can't put a cross on there, you cannot put a pentagram on it."
She pointed out just last month, Walgreen's pulled wrapping paper from its shelves because the images appeared to be swastikas.
"Would we allow a swastika, for instance, to be on the back of the bus?" she said.
She wants the lights replaced with solid signals.
A local Wiccan group says her claim is nonsense, adding while the symbol is used by satanists, it is also used for good. The school district didn't even bother to respond.
