OEM headlights and aftermarket headlights differ in quality. The housing of OEM headlights maintains its sealing performance for many years without significant aging, while the housing of aftermarket headlights tends to lose sealing performance and show noticeable aging over time. Headlights are a crucial component of a car, serving the primary function of illumination. Also known as car front lights or LED daytime running lights, headlights act as the 'eyes' of the vehicle, impacting not only the owner's external image but also safe driving during nighttime or adverse weather conditions. The use and maintenance of car lights are essential and should not be overlooked.

Why is water dripping under the Honda CR-V?

Engine water dripping is a normal phenomenon for drainage purposes. The relevant explanations are as follows: 1. Introduction: The exhaust pipe designed by the car manufacturer usually has a small hole for water drainage. Some exhaust pipes are designed with the tail end lower, allowing water to be discharged during driving. For some exhaust pipes with a lower middle section, the manufacturer will drill a hole at the lowest point in the middle to let the water out. 2. Additional note: While engine water dripping is normal, exceptions may occur, especially in mid-to-high-end vehicles, indicating that the engine is in good condition. However, if coolant from the engine leaks into the combustion chamber, causing the exhaust pipe to leak water, it is necessary to check whether the coolant tank in the engine compartment is leaking.
