Manufactured to o.e. specification

All of our Simply Auto range of bulbs are meticulously manufactured to an O.E. (Original Equipment) specification. The bulbs are made to the same blueprint as the factory-fitted originals, providing an exceptional value direct replacement. If you’re unsure what type of bulb you need to change, we would advise that you check your vehicle’s handbook.
