hi, i drive a 2006 Elantra with a stock horn - no modifications have been done with horn swaps or anything to it.
i also have a Cobra ESD 7400 radar detector that i bought recently.

I noticed that while beeping the car horn, the radar detector beeps, showing that it is reading a Laser gun.
I am sure that it is the horn, as i have tested it multiple times and was sure that it was not a real cop making my detector go off.

isnt this weird? i would not have expected my car horn to emit the frequency of a laser gun!
