There is no rule such that the bathroom lighting should be provided only in the ceiling or is better if it is provided at the sides or on top of the mirror. One has to fix the bathroom lightings according to one's taste and the mood that he or she wants to bring into the room. Even for a small bathroom, people, these days, go for two or more lighting fixtures. Thus, lighting is the most important factor to be considered in any modern bathrooms.
When it comes to lighting the interiors of your home, you cannot afford to ignore your bathroom. It is important to choose appropriate bathroom lighting that would not only provide illumination but also go with the décor of your bathroom. Bathroom lighting is a part of the broader category of home lighting.
If you want to look your best then you'll probably spend a fair bit of time in the bathroom, but unless you have decent bathroom lighting you may not be seeing yourself in the best light.
Also the light can be reflected by using mirrors if they are placed in strategic places and you can get better results when decorating the bathroom. It may also be supplemented by a lamp or lamps perched on the bathroom cabinet if the electrical system allows this. All these will help you to have a stronger light when needed, but also a dimmer light to create a romantic atmosphere.
