Will a broken headlight housing be affected by rain?

[McBryce]

Yes, it will be affected. The specific impacts are as follows: 1. Causing drainage holes to clog: Rainwater can block the drainage holes at the four corners of the window frame. If the rainwater is not drained in time, it will overflow and soak the interior trim panels around the sunroof or the sunroof switch. 2. Leading to water leakage inside the car: The drainage pipes, hidden inside the A, C, or D pillars of the car, are responsible for draining the water that flows into the drainage holes out of the vehicle. If the connection between the drainage pipe and the hole comes loose, the pipe itself is cracked or has holes, the pipe is bent too much, or the pipe is aged, it can cause water leakage. 3. Causing internal vehicle component failures: Water entering the vehicle can wet internal components, leading to short circuits in the internal wiring. If the rainwater has not dried, it may prevent the vehicle from starting.
