What’s the green light for on the Cavs of tankers
Think it’s to identify adr carrying vehicles .
I presume you mean the master switch light? It (and the cab roof marker lights on ours) goes out, so you (and any controllers/monitors) know that the vehicle is isolated, e.g. when loading.
It shows that your isolator switch is on, so that when you are loading, in the terminal, everone knows that you’ve switched it off for loading if the light is out.
