Flasher Warning

It is the final responsibility of the installer of headlight and taillight flashers to determine their compatibility with the vehicle make and model in which they will be installed. Incorrect wiring of flashers could result in costly problems or even permanent damage to the vehicle's computer module as well as injury or death to operators and bystanders. It is not recommended to alter a vehicle's factory wiring or to flash any factory installed lamps or bulbs. Strobe and LED lamps are available for this purpose.

As a side note, some police package vehicles are designed with the ability to have headlights and taillights flash. Read your car's manual to determine how to access this function.
