I can not see the lights in the TC servers. i could before i changed some graphics settings but after that I could not see them light up. I changed back to my old settings and still could not see them. I left and joined back and i still couldn't see them. Have not tried restarting LFS but i will try that now.
Can you please provide a screenshot.
You cant see any light? Have you checked all the lights?
I say this cause there are some lights which ones are on-demand only , and if anyone request them , are all the time off.
A user called ptfox had the same issue the other day:

He said "put when i putted textures to high then them diseappeared".
Restarting LFS should always be the first measure, even before asking for help. Nobody knows what LFS exactly does what you play around with those settings.
Oh, yeah. I forgot to mention that ptfox's issue was fixed once he restarted LFS..
