Since the last update to the game, all signals from the "European Content Pack" have been virtually "ruined." The filaments of the light bulbs are completely wrong (the previous ones were original, not replaced with something faulty), and the signal image is no longer recognizable due to the almost nonexistent luminosity (apparently, it's no longer compatible with the TOD system). Here's a comparison: on the left, the original Ks signal; on the right, the current faulty Ks signal.
