Hello everybody,

and so now to the result of the analysis and the final inventory control of the Crawler lighting, which is now fixed and can be seen in the following image, which however does not show the STS-6 Crawler, but the Crawler CT-2 that was upgraded for the SLS Program.

The total 29 Lamps of the former STS-6 Crawler are distributed as follows:

Driver's cabs: 2
JEL-Hydraulics: 8
Trucks (out-/inside): 8
Sidewalls: 2/2 Beacons
Front side (Side 3): 3
Back side: (Side 1): 4
And this result actually corresponds to my initial estimate of approx. 30 Lamps.

Just briefly to the explanation of NASA's designation of the front and back side of the Crawler, which was incorrectly named in my last post.

The crawler with the MLP drives from the VAB with the Side 3 (front side) in the direction of the Launch pad. Therefore from the south side on the pad one always looks at the Side 1 (back side) of the crawler, which then becomes the front side when it return.

The Side 1 of the crawler one can recognize, in difference to the Side 3, by the the stairs platform onto which the MLP stairs can be folded out, which is folded in again after the MLP has been set down onto the Pedestals, before the Crawler returns.
