These top-mounted, high-intensity lights on an LRV are called auxiliary lights. They serve as secondary lighting to boost visibility of the vehicle, especially in low-light conditions or at crossings, and they’re separate from the primary headlights or any warning devices. The term “auxiliary lights” is the standard label for these extra lights. The other options refer to broader warning systems or trackside signals rather than the vehicle’s own lighting, so they don’t fit as well.
