The big question: Spotlights or Spreadlights?
Most spotlights have a thinner angle, which means you can extend how far you can see when it's dark - so spotlights are the best choice if you'll mostly be driving at night on defined tracks needing longer visibility. Conversely spreadlights give you a wider angle of vision over a shorter distance, so they are better for lighting up spaces, obstacles and terrain closer to the vehicle.
