FIGURE 8-12 Runway centerline lighting (Federal Aviation Administration).
Runway touchdown zone lights are white, consist of a three-bulb
bar on either side of the runway centerline, and extend 3000 ft from
the runway threshold or one-half the runway length if the runway is
less than 6000 ft long. They are spaced at intervals of 100 ft, with the
first light bar 100 ft from the runway threshold, and are located 36 ft
on either side of the runway centerline, as shown in Fig. 8-13. The
centerline lights are spaced at intervals of 50 ft. They are normally
offset a maximum of 2 ft from the centerline to avoid the centerline
paint line and the nose gear of the aircraft riding over the light fix-
tures. These lights are also white, except for the last 3000 ft of runway
