You can test the new bulb by turning on the car and turning on the headlights. And then go around to the back of the car and see if the lights are red, if it is then that is great if not, that would suggest going back through the steps and see if you have properly inserted the bulb in the plastic and the hole itself as that is most likely where the issue is. Also, double check if you have the correct bulb as this is as important as following the steps.
