We always drive with our lights on, and if the dust is too bad, I will put my top spotlights on, allowing oncoming vehicles to see that someone is on the other side of the dust. I did have to go quickly off the road a couple of weeks ago, when a clown came through the dust of a road train, there is no way the driver could have seen through that dust.
Night driving around the Tanami at the moment is not a good idea, as the dust seems to be hanging around for a long time.
