West Tek Tactical Optics - Night / Thermal Vision
With the West Tek Tactical Optics installed on your console, you'll be able to create Night Vision, Thermal, and Targeting HUD goggles and eyepieces.
The new items are available in an assortment of colors and styles including an up-on-the-forehead version that won't obstruct your characters face.
If you roam around with Dogmeat, you can also slap a pair of googles on him if you decide he needs an upgrade.
To acquire them, you'll need to head to the Med-Tek Research Facility. These are particularly great for someone playing a stealth build.
