Fit bumper headlights
When I was doing a bit of mobile mechanicing, I used to have a spotlight on my parcel shelf so I could reverse up to something I was working on and night and see what I was doing. Before you ask why I didn’t use the headlights, it was easier to reverse up because my tools were in the back and I didn’t want to to run around the car every time. Used it on a few tailgaters and it works. Probably maybe definitely illegal but sometimes you have to fight fire with fire.
