“Headlights are too dim, with poor visibility at night, even when the fog lights are on. H road needs to be illuminated a little bit more, or even have a further beam. The LED version of the Civic has a excellent headlight pattern/brightness. However, lx, sport and ex share the same dim headlights at night. That is. A safety issue and can cause a crash, or hit something that should have been illuminated more.”
