How many LASER sets would you like on the FRONT of your car?
Stinger's Laser sets are all-fiber and come with one transmitter and one receiver.
Fiber Laser is nearly invisible on your car. Take into account that the more Laser sets on your car, the closer you get to 100% protection. And, the bigger your car, the more sets you would need for optimal protection. Know that most police officers shoot 'center mass' (license plate and surroundings), so often one Laser set will suffice. However, more experienced officers go for the headlights, in which case you would need two or, optimally, three Laser sets.
You can, of course, skip the configuration and go straight to the store.
