ALP Setup Guide Part 2: Deciding How Many Heads You Need

In this section we’ll cover how many heads you should get for your ALP. Choosing the correct number of heads is vital for solid performance. It also really matters where you install them on your vehicle as well as how you position the heads. Mess up any of these things and your jammers will not be able to do their job and protect you. Just because you have laser jammers somewhere on your vehicle does not mean that they will work properly! It’s like keeping food in your pocket and then wondering why your hunger isn’t going away. 🙂 You have to use your tools properly, not just have them on your car. Installing them properly is one of the most important things I’ll cover in this entire guide so please understand this thoroughly to make sure you know what to buy and how to install your jammers so that they’ll do what you want them to do.

Now in order to know how many laser jammer heads we need on our car and where they should go, we need to first know what the targets are on our vehicle and thus what we’re trying to protect.

Lidar Guns Targets on our Vehicles

Police officers are trained to target the areas of the car that are the most reflective and easiest for a lidar gun to get a reading from. Those areas are:

  1. Driver’s side headlight
  2. Center mass (grill or front plate if applicable)
  3. Passenger’s side headlight

Modern lidar guns are able to get a reading off of any part of the vehicle, not just the shiny parts. This includes the bumper, foglights, blacked out non-chrome grills, etc. However, installing our laser jammers such that they are ideally suited to protect the 3 primary target areas will also have the effect of protecting the rest of the car too.

How Many Laser Jammer Heads Do We Need?

Here’s a quick overview of how many heads you need for your vehicle, depending on the type of vehicle you drive, where you drive, and if you want front protection only or both front and rear protection. Some of the newer anti-jamming guns with a variable pulse rate (VPR) will require additional heads.

1 Head

  • Motorcycle, front coverage only, no VPR guns

2 Heads

  • Small to mid sized cars, front only
  • Motorcycle, front and rear coverage
  • Motorcycle with full protection against VPR guns, front only

3 Heads

  • Mid to large sized vehicles, wide sports cars, trucks, SUV’s, front only
  • Any car or truck that encounters VPR guns

4 Heads

  • Front and rear 2/2 protection for small to mid sized vehicles

5 Heads

  • Full protection for all vehicles against all guns, front and rear

2 or 3 Heads up front?

The front is the main area most people need to protect and in many parts of the country they only target the front of your vehicle. Here’s the general rule of thumb:

For small and compact cars, 2 heads will generally provide sufficient protection. Standard/mid-sized vehicles can often work well with just 2 heads as well, especially against older guns.

Midsize to large cars, including wide sports cars, as well as trucks and SUV’s would need 3 heads to fully protect the front of the vehicle due to their larger target areas.

Against some of the newest variable pulse rate (VPR) lidar guns that are designed specifically to defeat laser jammers, the ALP can defeat them with just 2 heads, but things improve greatly with a third head in the center of the vehicle and it’s for this reason that if VPR guns are in use where you drive, 3 heads are highly recommended.

Are VPR guns used in your area? Well they’ve most heavily used in GA and in Edmonton, Canada. I’m also aware of them currently being used in FL, KS, LA, MA, MO, OH, TN, & VA. In Canada they’ve also been spotted in Newfoundland. They may also be in use elsewhere and they continue to spread steadily throughout the country. Even if they’re not in your state yet, it would be safest to go for at least 3 heads up front for peace of mind, especially if you’re gonna be spending the time and energy to get everything installed anyways which can involve removing your bumper, running wires back through your vehicle’s firewall, etc.

If you need to order more heads, I recommend doing so before you start taking off your bumper, running the wires, etc. It’s much easier to do everything all at once. You can purchase more heads here.


AntiLaser PriorityThe ALP’s control box has ports for 3 heads up front. If you’re running only 2 heads up front, make sure you’re using only ports F1 & F2. Don’t plug either head into the F3 port.

If you run 3 heads up front, the center head MUST be plugged into the F2 port of the CPU. It doesn’t matter if the left or right head is in F1 or F3, but the center head must be plugged into the F2 port in order to jam those VPR guns properly.

Rear Protection?

Do you need protection in the rear? Some places shoot only the front, some places shoot both front and rear. In other places they shoot only in the rear. There isn’t really a comprehensive list of what’s in use where. However, most places around the US focus on the front and it’s for that reason that front protection is considered standard and rear is generally considered extra for complete protection.

If you can afford it, I’d recommend front and rear for full protection. It’s a few hundred dollars more for the heads plus a more involved install, but should you encounter rear laser, you’re going to be glad you protected your rear. 😉

    I am looking to buy a 2018 Mustang GT. Just wanted to know which AL Priority package I should purchase how many sensors ? And I need to have it installed by a professional installer around Columbus Ohio USA.

    1. Vortex

      In the article it states that you’ll need 3 heads up front. If you also want rear protection (generally a good idea), you’ll want to choose 5 heads instead.
