To replace the rear number plate light bulb, you need to remove the lamp holder: this is clipped to the bumper via two plastic tabs; simply widen the tabs slightly to pull it out. At this point, remove the old bulb (T5 fitting) and insert the new one. Check the bulb is working: if it does not light up, ensure the correct voltage is reaching the lamp holder; otherwise, inspect the power cable which, due to its positioning, may be subject to damage.
