I'm quite certain the Texas contingent will be here shortly, but in West Texas at night...
It's DARK - real dark!
I did a 50CC across I-10, staying in 'beautiful' garden spot of Van Horn, TX in mid-October. When I could use aux lighting, I did, but when it was not easily done (oncoming traffic), I simply rolled back and stayed pretty close to the speed limit.
Luck to ya!
