What are the reasons for water leakage in interior lighting?

Here are the reasons for water leakage in interior lighting: 1. If there is a sunroof, it may be due to issues with the sunroof section, roof welding points, or rust perforation, which can cause water leakage. 2. There may be gaps in the adhesive tape on the outer glass of the windows. 3. The sunroof may not be tightly sealed, leading to rainwater leakage, or there may be areas on the roof where the seal is not tight. Here is some related information about interior lighting: 1. Interior lighting includes instrument panel lights, ambient lights, and roof lights. 2. Most interior lighting has two types of switches: one is a manual switch, usually located next to the light, which can be pressed directly to turn the light on or off; the other is an automatic switch.
As a long-time car owner, I find that interior light leakage is quite common, especially in models with sunroofs. The most prone to failure is the sunroof sealing gasket, which hardens and ages after a few years of use, allowing rainwater to seep through the gaps. Another common issue is the sealing strip above the door. If it's not securely installed or becomes worn and cracked, water can leak into the light housing during rain. I've experienced this myself—blocked drainage holes caused rainwater to back up, nearly damaging the electrical circuits. It's advisable to inspect the sunroof and door seals every six months and clear any leaves or debris from the drainage holes. Addressing these issues early can prevent worse outcomes, such as mold growth inside the car or electrical short circuits, which increase repair costs and compromise driving safety. Remember, performing minor maintenance before the wet season is the best way to save money and hassle.
