If the skies are crystal clear, the lights will be visible from anywhere you can see the summit of Mt. Washington, a radius of about 130 miles from the mountain.
Your ability to see the lights with the naked eye will vary based on proximity to the mountain and light pollution surrounding you. For best results, view them from somewhere with little to no ambient light. Long exposure photos and night mode on your phone's camera will often reveal the beams even when your eyes can't see them.
The lights are placed in a north-south line on the summit. Viewing the lights from the east and west (examples: Pinkham Notch on the east, Bretton Woods on the west) will allow you to see both columns clearly. Viewing from the north and south, especially at distance, you may see the columns appear as one column.
Popular viewing spots in the Mt. Washington Valley will be:
The Intervale Scenic Vista Rest Area, Intervale, NH
This is a state rest area and visitor center with a beautiful view of Mt. Washington.
Hotel Indigo's Viewpoint Rooftop Eatery & Bar located across the street from the rest area has a panoramic view with Mt. Washington in the center. From September 9-12, first responders enjoy 25% off orders at the Viewpoint Eatery + Bar.
