Reasons for one side of the Honda CR-V rear taillight not working: Possible short circuit in the wiring on one side: There may be a short circuit in the wiring on one side, such as aging wires or poor contact at the connectors; aging wires can be replaced with new ones. Bulb failure: If one brake light is working and the other is not, this issue is usually caused by the brake bulb. Replacing the brake bulb can resolve the problem. Precautions for replacing brake bulbs: When replacing brake bulbs, it is recommended to replace both at the same time to prevent uneven filament erosion, which could lead to one light working and the other not. However, the owner can keep a good bulb in the car for emergencies. Reasons for the car brake light staying on: Issues with the brake circuit or sensor, indicating a problem with the brake wiring or sensor. Insufficient brake fluid in the car. Significant wear on the brake pads or intermittent functioning of the brake light, etc.
My old CR-V had a similar issue before—one of the rear taillights suddenly stopped working. The most common cause is a burnt-out bulb; just replace it with a new one that matches the correct model, like an H11 bulb. Another possibility is a blown fuse. The fuse box is usually located under a small cover to the lower left of the driver's seat—find the fuse corresponding to the taillight and replace it. Wiring problems are also quite common, such as a loose or corroded connector preventing current flow, so inspect and clean it if needed. A faulty relay or aging socket can also cause this, though less frequently. As someone who's driven for over a decade, I must warn you: driving with a non-functional taillight is extremely dangerous, especially at night, as it increases the risk of accidents. Address it promptly—don't delay. During routine maintenance, take a moment to check the bulb's condition; it can save you a lot of trouble later.
