I had the settings to keep the game updated, but had an issue with R5, causing me to uninstall and re-install the game. Upon doing so, there were some nice new features and fixtures that I realized I had been missing out on; at the same time, there was a headlight fixture that no longer was available. These concealed headlights work on models such as this, and are no longer available. Although there are new popup headlights, these worked for me.
Those looked like that because they were broken. You can set the glass to be the same colour as the body for a similar effect.
