I remember reading here that they were EMERCOM lights. And I believed that and sticked to this idea for a while. But so far I haven't seen a single photo with them in this role. Only those pointed upwards.
Maybe the standard EMERCOM lights (obviously portable)
have been put on the poles remaining from the former ALS,
now defunct and non-operational since years (looking on their condition),but certainly not an ALS system available at the moment of the Tu-154 landing.
So what happend to the old ones then? How different they were?
Either the plane landed to these on these pictures or...
... there were no lights (?!).
Anyway, from the blog linked above it turns out pilots did not see any lights until they crashed.
