How many lights are in the Heathrow runway?

What do the lights next to the runway mean?
These are VASI lights, which stands for Visual Approach Slope Indicator. When approaching a runway to land, an aircraft follows a specific glide slope. Usually, that slope is around -3 degrees. These VASI-lights help the pilot visually verifying that they are not too low and not too high.
Why is Heathrow closed at night?
Night-time (23:30 – 06:00) operations at Heathrow are heavily restricted by the Government, which sets a limit of 5,800 night-time take-offs and landings a year. A night quota limit is also in place, which caps the amount of noise the airport can make at night.

Airport taxiway lights are always blue. These lights guide the flight crew and vehicle drivers in low visibility conditions, which includes nighttime operations. In the dark, humans best see the color blue green, which is why taxiway edge lights are blue and centerline lighting is green.
