No matter the front or rear fog lights, the principle is actually the same. So why are the front and back fog lights different colors? This is how to adapt to local conditions. In most cases, rear fog lights are red, so why not white rear fog lights? Since the reverse lights had already been "pioneered", red was used as the light source to avoid miscalculation. Although the brightness is similar to brake lights. In fact, the principle is not the same as the effect is not the same, in the case of too low visibility should open fog lights to supplement lighting. Make it easier for cars coming from behind to find out.
