What does a bulb with an X symbol indicate as a fault?
1 Answers
It indicates a faulty brake light bulb. Here are the relevant details: 1. Brake light location: Brake lights are generally installed at the rear of the vehicle, with red-colored lenses to enhance light penetration. This ensures that following vehicles can easily detect braking actions even in low visibility conditions, helping to prevent rear-end collisions. 2. Precautions for replacing brake light bulbs: Vehicle tail lights typically serve dual purposes ('one bulb, two functions'), containing two filaments inside - the weaker one for parking lights and the stronger one for brake lights. Some manufacturers design them as high-low pin plug-in types for user convenience. Special attention must be paid during replacement to avoid incorrect installation.
