BlackBerry Pearl freaks out a rechargeable flashlight

This is weirdly interesting.

My Pearl is about 2 years old.. and a refurb. It’s always done weird things when too close to speakers – makes them sputter out all kinds of noise due to its radio antenna signals. Last night I discovered a new.. “trick” this thing has. I put it next to a rechargeable LED lantern/light and suddenly it started blinking WILDLY. When I moved the BB away, it stopped. The light is controlled by a physical button, and to my knowledge does not have any radio controls.

Has something like this every happened to anyone?  I get the radio and speaker thing all the time, but never has my BlackBerry freaked out another electronic device let alone turn it on.
