Can Two Rear Fog Lights on the Octavia Illuminate?
2 Answers
Octavia cannot have two rear fog lights illuminated; only one rear fog light can be turned on normally. The function of car fog lights: Car fog lights are used to illuminate the road and provide safety warnings during rainy or foggy weather, improving visibility for the driver and other traffic participants. Fog lights generally refer to car fog lights, which are installed on the front and rear of the vehicle. Classification of car fog lights: By installation position, they can be divided into front fog lights and rear fog lights. By light-emitting principle, they can be categorized into gas car fog lights and LED car fog lights. Audi has recently developed a laser fog light.
I've worked on quite a few Octavia rear fog light systems. The factory design only allows one to illuminate, located on the left side of the vehicle. Regulations require rear fog lights to be single-sided to avoid confusion with dual brake lights and prevent misjudgment. When inspecting the wiring, I often find that the right-side position is actually a reflector with no bulb socket at all. If you really want to modify it for dual lights, you'd need to rewire, and also consider waterproof sealing and relay load, otherwise it's easy to blow a fuse. My advice is not to bother—the factory fog light brightness is sufficient to penetrate thick fog, and modifying to dual lights may fail the annual inspection and could be illegal. If you encounter the right side not lighting up, it's completely normal—it was designed to be single-sided from the start.
