Will water enter if the side mirror turn signal has cracks?

This requires testing to know. It is recommended to observe for a period of time. If water enters during car washing, simply replace the side mirror turn signal. Below is more information about side mirror turn signals: 1. Introduction: The turn signal is an important indicator light that is turned on when a motor vehicle is turning to alert vehicles and pedestrians in front, behind, and on the sides. The turn signal tube uses a xenon tube, controlled by a single-chip microcomputer circuit, with alternating left and right flashing for uninterrupted operation. The turn signal uses a flasher to achieve light blinking. It can mainly be divided into three types: resistance wire type, capacitor type, and electronic type. 2. Function: It makes it easier for vehicles or pedestrians traveling side by side to notice the vehicle is turning and to yield in time.
That cracked turn signal on the side mirror can indeed let water in easily. Having driven for over a decade, I've encountered this issue myself. Even a tiny crack allows water to seep in during rain or car washes. The housing, originally well-sealed, now lets water and dust inside, damaging the bulb and wiring. Winter makes it worse as freezing water expands the crack. A waterlogged turn signal may fail to flash, compromising turn signals and potentially causing fuse blowouts from short circuits. I recommend checking the crack depth—if noticeable, replace the housing promptly at a repair shop to avoid costlier fixes later. Park in shade when possible to reduce plastic aging. Safety first: malfunctioning turn signals pose serious risks, especially at night.
