So I found this little black box on my tail light, it was stuck on there by some kind of grey tack. It had a bell-shaped hole on it and I could tell there was something inside. I cracked it open and found a circuit board wired to a piezo disc and a long green tube that had copper wire wrapped around a graphite rod. The hammer did some work to it so it's a little busted, but here is the pic of the remains.
Is this a tracking device or what? Kinda worried.
