What does a brake light bulb do?

A brake light bulb is responsible for lighting up your brake lights when you apply the brake pedal. They are a crucial safety feature of your car, letting the people behind you know in plenty of time when you’re about to slow down. It’s a good idea to regularly check that all your brake lights are clearly visible and in good working order.

How often should brake light bulbs need replacing?

As with any car part, the quality of the bulb and how often it is used will determine how often the bulb needs to be replaced. Some bulbs can last for up to five or six years (traditional, incandescent bulbs). However, more modern LED bulbs have a life expectancy of around 12 years. Another factor that can affect the life of the vehicle is the amount of voltage running through the wiring. The higher the voltage, the shorter the lifespan of the bulb.
