It all depends on which producer you have in your car. Even if you still have original lamps, depending on the manufacturer, the method of replacing the bulbs may differ significantly so I recommend adding a reflector.
The lamps I have are ordinary, not lenticular, I was looking for some signs on the headlamp there are some numbers on the plastic and that's all, Are you telling me to look for a replacement description in the instructions?
