What causes water ingress after modifying the Santa Fe fog lights?

The main reason for water ingress after modifying the Santa Fe fog lights is the poor quality of the fog lights. Here are some details about fog lights: 1. Fog lights are divided into front fog lights and rear fog lights, with differences in color, typically yellow for the front and red for the rear. 2. Their characteristic is that the light has strong penetration and does not produce diffuse reflection due to fog, which can alert other vehicles and improve visibility during rainy or foggy weather. Additional content: The method for replacing Santa Fe fog lights is as follows: 1. Before installation, ensure the car is parked and turned off, preferably on a road with a slight slope, and engage the handbrake. 2. Open the engine hood, disconnect the fog light switch, unplug the fog light power supply, and disconnect its power system. 3. After removing the washers, screws, and nuts, the fog light cover can be taken off, and the old light can be removed. 4. Install the new fog light; when correctly installed, the fog light should fit snugly into the mounting position. Place washers on the screws, then tighten the nuts with a ratchet wrench or adjustable wrench to secure the fog light. Finally, plug in the fog light power supply.
As someone who frequently researches car modifications, I believe that water ingress in modified Santa Fe fog lights is mostly due to inadequate sealing. During modification, the waterproof adhesive around the lamp cover may not be applied evenly, or aging seals may create gaps, allowing moisture to easily seep in. Sometimes, the issue lies with the quality of the aftermarket parts themselves, which have poor waterproof designs and reveal their flaws under high-pressure car washes or rainy conditions. This isn't just a cosmetic problem—it can affect light brightness and bulb lifespan, and in severe cases, cause short circuits in the wiring. I recommend checking the edges of the lamp cover after each modification to ensure tight sealing, and ideally, having a professional double-check it. Regular maintenance can also reduce such issues, such as avoiding direct high-pressure water spray when cleaning fog light surfaces and keeping drainage holes unobstructed.
