This can be deleted, but it will reappear. However, the brake light is working. Is this a known issue? I suspect the circuit board is failing.

Hello,

The original taillights (without LED) are prone to water leaks.
The contacts of the bulbs can oxidize, but a tiny dab of copper paste on the bulb's contact can help. Don't drip or splatter, or there will be a short circuit.
And sometimes, simply replacing the bulb is enough. Sometimes, the filament isn't properly secured to the base, which can cause the bulb to work intermittently.

Sure, here's the translation:

"LG" translates to "Best regards" or "Sincerely" in English.
