Why does the Avalon only have one reverse light?

The reason why the Avalon only has one reverse light is that this model is equipped with only one reverse light. The reverse light is installed on the right side of the rear of the car, making it convenient for the driver to reverse and park on the right side of the road at night. It is used to illuminate the road behind the car when reversing and serves as a warning to vehicles and pedestrians behind. The specific introduction of the Avalon is as follows: 1. Interior: The 2021 Avalon adds a leather steering wheel to the interior. The visual impact of the red and black sport seats will not make people feel dull. The 9-inch central multimedia touch screen supports Baidu CarLife, AVS adaptive suspension, ambient interior lighting, electric sunshade, JBL surround sound system, and other configurations, providing a very comfortable driving experience. 2. Power: The 2021 Avalon is still equipped with a 2.5L naturally aspirated engine, with four adjustable driving modes, a maximum power of 210 horsepower, and a maximum torque of 250 Nm, matched with an 8-speed automatic transmission, meeting the China VI emission standard. According to the official claim, the comprehensive fuel consumption per 100 kilometers is 6.2 liters.

I've been driving the Avalon for several years and noticed that indeed only one reverse light is on. This is not a malfunction, but rather a deliberate design choice by Toyota. The primary reasons are cost savings and reduced circuit complexity. Many modern vehicles install a reverse light on one side and a reflector on the other – one light is sufficient to illuminate the rear during reversing while also simplifying wiring and reducing potential failure points. This design complies with regulations, and tests show that a single light provides adequate brightness without compromising nighttime reversing safety. However, as an owner, I sometimes mistakenly thought the bulb was burnt out when it's actually the standard configuration. If both lights were on, that would actually indicate a need to check fuses or wiring. The Avalon's design follows this mainstream trend – models like the Accord use similar setups. Just have your technician confirm during regular maintenance; no need for unnecessary concern.
