What causes the interior lighting to leak water?

[LilyFitz]

Water leakage in the interior lighting is caused by rust penetration in the sunroof area and roof welding points. Here is an introduction to the relevant content: 1. Function: Interior lighting is installed in various parts of the cabin to facilitate safe entry and exit at night and for reading maps while driving. In passenger vehicles, interior lights are generally installed in the center of the cabin. Ideally, they should evenly illuminate the entire interior. To reduce the thickness of the lights, 5~10W tubular bulbs are commonly used. For spacious interiors, bulbs with a power of 8~30W are typically used to meet lighting requirements. 2. Light source: In some lighting fixtures, LED light sources are adopted for their slim profile and energy-saving benefits.
