Airbus FCOM says: When crossing a runway: Strobe sw.... ON and Runway turn off lights..... ON. Period. No TCAS, it's forbidden due to potential interference and no other lights. I don't understand why some airlines like to supersede Airbus SOP. If you don't see an aircraft with his strobe ON, something is terribly wrong. By the way the wing light is annoying for other traffic taxiing nearby. xD

I'm not sure about the SoP for all carriers, but one thing hinting us as ATC, is that some airlines turn on landing lights when being given an take off clearance.

The LAND = ON upon receipt of TKOF clearance in the Cookbook was a change about 7 years ago, to align the generic manufacturer's guidance to the industry best practice from the FAA land. Before, a more grass-root level concept prevailed: as little actions on the runway as possible (to be done when entering the runway).

For me using TCAS = ON for crossing a runway is the smart choice, similar to displaying LS=ON briefly during line-up in LVP. May not be up to date on the latest print. The technical reasons for disallowing TCAS on the ground are not in conflict with its use for crossing the active.

2 side remarks done

You may be surprised how strobes can be missed, as they were on 24L at LAX to the detriment of the Metro and 737.
