Ferrari SF71H F1 2018 In Action - Strange Test Lights, Rear Smoke, Wastegates Opening & More!

The last (but not the least) video from the 2018 Formula 1 official tests I show you is entirely dedicated to the Ferrari SF71H.
I could have chosen one of the others cars but during my 2-days stay in Barcelona I found some curious and strange things being tested/used by Ferrari. But first thing first.

Halo, narrow and tiny sidepods, those curious mirrors. Don't want to talk about them. I want to focus your attention on a few things I saw when the SF71H was out on track and I really hope some of you give me an explanation for point 2 and 3 just for pure curiosity ;)

1) Needless to say it but wastegates (or whatever it is) were opening quite often, increasing the sound of the V6 engine. First time I noticed on a Ferrari's PU to be honest (Renault and Honda's power units were more likely to do it, but I rarely heard them too last week). Of course same thing for Haas and Sauber-Alfa Romeo, but the increase in sound was much lower. Still try to understand if it's a good or bad.

2) During the second day, temperatures were really low in the morning so teams took advantage of that situation by doing some "data collection" works by using aero rakes to study airflow in and around the car. Ferrari did a few slow laps (without any aero rake) and I noticed two bright lights in the back of the car, under the diffuser and near the two rear tires. At first I thought they were just some strange reflections caused by the sun but changing my recording place I understood they had to be lights. Anyone knows what are they for? 6:15, 6:22, 6:32

3) This is another curious thing. It's characteristic of all Ferrari powered cars (Ferrari, Haas and Sauber) and it's that soft and subtle cloud of smoke/vapor you can see coming out from the rear impact structure, just under the red led light. Noticeble every time, slow/high speed sections or even when it's stopping in the pitlane. You can notice it if you freeze the video at 2:08, 3:20, 3:37, 4:46...10:09. Explanations?
