However, Feng Shui is not a science, but a cultural tradition and belief system. The concept of Feng Shui varies greatly in different regions and cultures, and there is no conclusive evidence to prove its effectiveness. Therefore, the choice of safety light location still needs to be based on personal preferences and actual needs.
If you pay attention to feng shui and have a special preference for installing lamps on the west side, then choosing the position of lamps according to the theoretical principles of feng shui may bring you better psychological feelings. But if you are not interested in Feng Shui, or have no special beliefs, you can choose the position of lamps according to your own aesthetic and practical needs.
To sum up, the installation of lights on the west side is considered to be beneficial in geomantic omen, but it needs to be considered comprehensively according to personal preferences and actual conditions. I hope this answer is helpful to you.
