What to Do When Daytime Running Lights Get Water Inside?

Remember to first remove or completely disconnect the power supply of the LED strip lights. Use a hairdryer at maximum speed to dry them, and you can appropriately alternate the hot air back and forth. For severe areas, use tissue paper or cotton swabs to absorb the water. Then, use the hairdryer to blow air directly close to the gaps, trying to dry the water inside as much as possible. After drying, if the LED is quite hot, let it cool down before testing if it can function properly.
The other day my car's daytime running lights also got water inside, the lens was completely fogged up. This is no small matter and needs immediate attention. First check if there are obvious cracks or impact marks on the lens - even small cracks can let rainwater seep in. If the housing is intact, it's likely the sealant has deteriorated. Find an auto repair shop to disassemble the light assembly, use an air gun to thoroughly dry out the moisture, then reapply high-temperature resistant sealant. Let it cure for half a day before reinstalling. If the lens is significantly cracked or the circuit board is already corroded, you'll have to replace the entire unit. Don't try to save small money by delaying repairs - if a short circuit burns out the wiring, it'll cost much more to fix and make night driving dangerous!
