The reversing light switch of the Lavida is located on the vehicle's transmission. When the car is shifted into reverse gear, the reversing lights at the rear of the car will turn on to alert pedestrians and vehicles behind. The reversing lights are installed at the rear of the car to illuminate the road behind during reversing and serve as a warning to vehicles and pedestrians behind. The Lavida is produced by Shanghai and is equipped with an engine coded as EA211, which is a 1.2L turbocharged four-cylinder engine featuring direct fuel injection technology. Both the cylinder head and block are made of aluminum alloy. This engine delivers a maximum power of 110 horsepower (81 kW) at 5000 rpm.

Last time I helped my friend fix the reverse lights on his old Lavida, I specifically researched the location. The reverse light switch on this car is hidden on the side of the transmission, and you have to crawl under the car to see it. It looks like a small mushroom head, with a metal casing and a plug connected to the wiring harness. It's usually installed on the transmission housing near the cabin, not far from the shift lever cable. Just a heads-up, older Lavida models might require removing the underbody cover first to access it. When searching, focus on areas where wires gather—a black cylindrical component with a single wire connected to it is most likely the switch. If the reverse lights don’t work but the brake lights are fine, chances are this part is faulty or the plug is loose. Remember to engage the handbrake and use wheel chocks when working under the car—safety first.

We female drivers can't understand those complicated transmission structures. Last time when the reversing light of my Lavida didn't work, I was really anxious. The mechanic said the switch was under that iron lump between the engine and driver's seat, and you had to crawl under the car to reach it. He showed me with a flashlight - it's a black cylinder about finger-thick protruding from the side of the transmission, with wires connected. The mechanic said this switch is extremely sensitive and would fail with just a little transmission oil leakage. Sure enough, replacing the switch fixed it, and we did transmission too. By the way, if your reversing camera suddenly shows static snowflakes, it might also be caused by poor contact of this switch. Now I always check if the rear lights are on before reversing.

The location of the Lavida's reverse light switch is actually quite simple. It's mounted on the transmission housing, generally on the firewall side of the engine bay. If you're looking for it yourself, first turn off the engine and engage the handbrake, then crawl under the car with a flashlight. Locate the silver transmission housing and follow the shift linkage downward – you'll find a black plastic component about 2-3 cm in diameter with an electrical connector nearby, that's the reverse light switch. On newer Lavida models, the position might be slightly higher and accessible without removing the underbody panel. If the light isn't working, don't rush to buy a new switch immediately – try spraying some WD-40 on the connector first. Last time mine failed, it was just due to connector oxidation which was fixed after cleaning. Repair shops love to push customers into replacing the entire switch assembly unnecessarily.

Honestly, a faulty reverse light switch doesn't just affect illumination—it's even more dangerous because it can cause the reverse radar to fail as well. In the Lavida, this switch is located on the right side of the transmission, midway and adjacent to the driveshaft dust cover. For the average car owner, replacing it themselves is quite challenging, requiring a 22mm open-end wrench for removal and installation. Most critically, the hole in the transmission housing where the switch mounts must be completely sealed—I've seen cases where improper replacement to transmission oil leaks. Also, a heads-up: when buying a new switch, make sure it's a genuine OEM part, as aftermarket ones might fail within three months. And if you notice the reverse camera flickering when shifting into reverse, don't doubt it—that's a clear sign of poor switch contact. For safety's sake, it's best to have a professional handle the issue if you spot any problems.

When I worked on modified cars, I disassembled many transmissions. The reverse light switch for the Lavida is embedded on the side of the transmission housing, usually closer to the driver's side. The exact location is about ten centimeters behind the shift linkage rod, with a single wire connected. If you're replacing it yourself, prepare an oil drain pan—removing the old switch might leak some transmission fluid. When buying the switch on Taobao, remember to choose the version with a copper washer, which costs around 40-50 RMB. During the operation, first unplug the connector, then use a socket wrench to turn it counterclockwise. Before installing the new switch, wrap the threads with PTFE tape to prevent leaks. Once, during a modification, I forgot to plug in the connector, and the reverse camera stopped working immediately, so always test the lights after installation. It's also a good idea to check if the wiring harness has been melted by the exhaust pipe.
