Have a similar set of lights in the door pocket for similar such occasions. Tend to angle them down to the road a little as they’re fairly bloody bright, but..touch wood, haven’t had anyone run into the unit or trailer overnight yet.
The next task is to figure out some way of mounting them.
The front one will probably fix on the front grille, but I want to clamp the back one on the back end to defeat the light-fingered folk . Trying to work out something that involves box section, but the light will need to be removable for charging, and a g clamp with the t-bar cut off and replaced with a hex nut. Of course, it's entirely possible that as usual I'm overthinking things .
