Which type of bulb would you use when required to change a bulb in the vehicle?
- It is permitted to change a bulb in a certified licensing facility only.
- Correct answer: A bulb, stipulated in the manufacturer’s manual.
- It is prohibited to change a bulb without the permission of the treating garage.
- The type of the bulb is unimportant, as long as it works.
Why this is the answer
The correct answer in the official bank: A bulb, stipulated in the manufacturer’s manual.
Always fit the bulb type stated in the vehicle manufacturer's manual. The manufacturer matches each bulb to the lamp housing, lens and electrical system, so the light has the correct strength, colour and beam pattern. A bulb that merely works may dazzle other drivers, light the road poorly, overheat or damage the wiring. You do not need a licensing facility or garage permission to replace a bulb yourself.
