Question:
Is the magnet hold on these lights able to withstand a truck moving 60 mph down the freeway?

According to my technical contact at Custer, the Amber LED Safety Light that will withstand a truck moving 60 mph is # HF18A-HD. This unit has two, 25-lb pull magnets which gives you 50-lbs of pull, which is plenty to stay connected while highway driving.
The # HF18-MB that you referenced has two 10-lb pull magnets which are more for identification of your location when stranded or sitting on the side of the road.
