First of all, ETT is working correctly and as intended, just like we explained it to you in your previous thread that got locked for your insuferable behaviour:
https://forums.frontier.co.uk/showthread.php/297497-EET-display-is-useless
Second, when in supercruise, the space your ship is occupying within the warp bubble is moving at subluminal speeds, therefor your lights are also working correctly and as intended, just like I told you in your previous thread, read about Alcubierre Drive theory before parading your lack of education on forums and then when you get schooled - having to pretend you're a troll that has an alternative agenda, so you can keep your ego intact when you get your little feelings hurt.
Since we answered your question, and you already received and infraction yesterday, I'm reporting this thread immediately just to save you from yesterday's levels of embarasement.
You're welcome

The moment we go beyond 1c it generally becomes a 'maybe' if we try to factor out anything.
The main thing though with these drives that Elite use, is that they are what is called Alcubierre drive, read more: https://en.wikipedia.org/wiki/Alcubierre_drive
You are essentially in a bubble, and within that bubble itself you are not actually travelling above light speed. Thus avoiding all those pesky can't go faster then light, problems.
It gets complicated fast, how 'exactly' the moment happens in relation to space/time, but essentially you move through that rather then physical space. So yeah you can have headlights in your own reference frame, no problems, what could be argued looking weird is how we see other npc's and players when flying around in super cruise, right now its mostly cone behind and cone in front, and could maybe be tweaked slightly, personally I think there needs to be some lens distortion around them?
Guys, knock off the personal comments. I can't whack you, but other mods who are not involved can. Otherwise i'd have been handing out infractions like candy around here.
Go over his previous thread that lasted for 12 pages, he's just posting this out of pure spite for getting spanked yesterday, this thread needs to be closed immediately and OP sanctioned
Headlights come on automatically when in SC - they're what cause you to slow down along the route. They function like burning forward thrusters at FTL.
Which, as has been said, is not really FTL, it's spatial compression that only resembles FTL and those C+ velocities are purely relative.

Wait. Doesn't that mean they ARE the retro stabilizing thrusters and OP is confusing them for running lights?
Indeed.
Or, perhaps everything in front of you should be red shifted, and everything behind, blue shifted. All to verying degrees based on your percentage of the speed of light... and of course, once you exceed 1c, space dust ought to start eroding your shields while you leave a trail of explosions behind you (mass of the particle times the speed you are traveling, squared equals energy released). Yeah!
[yesnod]
I have an interest in science but I'm not all that clever. I'll give this a try though.
Firtstly. Faster than light travel is not currently possible as far as we know.
Secondly. I think that "general relativity" comes into play with the headlights.
So for a stationary observer you would probably be invisible. Or maybe just a flash of light.
However since you are travelling at the same speed as the ship....... the ship and its headlights would appear to be functioning normally to you.
For example if you were in the back of a pick up truck doing 200 kph and you fired a pistol out the front of the truck. The bullet would appear to be travelling at normal speed relative to your point of view. However, somebody standing on the side of the road watching you would think you were crazy....... LOL, sorry could not resist that...... They would think that the bullet was travelling 200kph faster than normal.

Well that's an interesting theory
Thirdly. Light is a consent. It's not like your bullet example in that it passes and then leaves. If it did then we would all go blind. Except that light is constantly emitting and therefore constantly present everywhere as long as things don't physically block it to cause shadow.
If your headlights are constantly emitting light then it doesn't matter how fast you're going. You eyes will run into the light and allow you to see rather then the light striking your eyes.
Technically (I do like posts that start with technically) c is not "the speed of light". c is the "cosmic speed limit", that is, the fastest speed at which matter/information can possibly travel in the universe (in a vacuum, that is). There's nothing special about light that means nothing can travel faster than it - light travels at c because nothing can travel faster than c. Hypothetically, light would travel at infinite speed if it could. Interestingly it's possible for particles to travel faster than light can in dense media like water (see Cherenkov radiation). Such particles are travelling faster than light in that medium, but are still slower than c.
I realise this is a troll post (when did immersion become a dirty word? Who actually doesn't want games to be immersive?) but hey, teh sceince.

And again something learned, I didn't know particles can be faster than light in water for example. Thanks!
No. Light can not travel slower than c. Any time that you think it does, it is simply not traveling in a straight line and that gives it the appearance of traveling slower but it is still traveling at c.
Hi, you are employing wrong sciences here.
Firstly, nothing can travel faster than light, it's simply not allowed by this universe (maybe there are universes that do allow it but not this one)
A photon (that does travel at the speed of light) when born is immediately transported to it's destination , that is the speed of light.
Let me elaborate, when a photon is born in our Sun, everything and everyone in the universe will agree that the photon is taking time, or traveling untill it reachers earth and get's absorbed for example on your face, warming you on a sunny day.
Same thing with photons that are born in the other side of the galaxy which are currently taking thousands of years to reach us, THE OBERSERVERS, judging by our point of reference.
But, for the photon, it's life span is completely different. It is born on the other side of the galaxy, and is absorbed by it's destination (for example your face)
immediately.
Therefore, not only it is not possible to travel faster than light, a statement "faster than light" is a logical fallacy, it's almost the same as saying "faster than the speed of 3 Isaac Neutons divided by 7 Conan O'Briens", it's as gibberish sentance, as you cannot build a craft from particles that don't even exist for longer than a split moment.
Theoreticly it's even impossible to build a craft that will travel at the speed of light. (however on paper i think it still possible to reach something like 99,99%, don't quote me on this as I do not remember now)
However, there is a way to cheat this, by employing Alcubierre's Drive theory, which is not technicly fictional as it has been proven on paper (the same way that Black Holes were proven years ago but were considered fictional untill their discovery by LIGO in late 2015)
Alcubierre drive theory states that you can build a craft with an engine that uses energy to contract spacetime itself ahead of the craft while expanding it behind the craft :
Allowing the craft to ride the wave of spacetime (as if a surfer would employ a surfboard to ride the ocean wave) and achieve superluminal speeds.
However, here's the interesting bit, the spacetime within the warp bubble would remain unchanged, therefore technicly the craft itself would not be traveling faster than light, even though the bubble itself would be, so yes you can have your headlights shining without the need of breaking the laws of physics.

Getting off topic now, but I'm genuinely curious:
According to https://en.wikipedia.org/wiki/Cherenkov_radiation, "the speed of the propagation of light in water is only 0.75c." Also, according to http://math.ucr.edu/home/baez/physics/Relativity/SpeedOfLight/speed_of_light.html, "Light is slowed down in transparent media such as air, water and glass."
I read that as light traveling below c in different media in non-vacuum?
The technically correct way would be to say that they are faster than the propagation velocity of light in water. Light is still traveling at c, but it now has to bounce off all the water molecules in its way. That slows it down from our perspective to 0.75c, but between the individual water molecules it is still traveling at c.
Hopefully this example helps clarify it for some people here
