What is the model number of the Langdong's taillight?
3 Answers
The model number of the Langdong's taillight is T10. Taillights are used to alert vehicles behind that there is a car ahead during nighttime driving and to indicate the positional relationship between the two vehicles, hence they are installed on both sides at the rear of the car. The design principle of taillights is to have sufficient luminous intensity so that the taillight signal can be clearly discerned by other drivers or pedestrians even in bright daylight; during nighttime driving, the light emitted by the taillights should not cause glare or discomfort to other drivers or pedestrians. The Langdong is a compact sedan with body dimensions of 4570mm in length, 1775mm in width, and 1445mm in height, and a wheelbase of 2700mm. The Langdong uses a MacPherson independent suspension for the front and a torsion beam non-independent suspension for the rear.
Speaking of the Lanos tail light model, I've been driving this car for several years, and the most common bulb used for the tail light is usually the P21W. The brake light part is P21W, while the position light might use something like W5W. However, the model varies depending on the car version; for example, my 2014 model is different from the newer ones. You'll need to open the engine hood or remove the trunk liner to check the number markings on the old bulb directly, or flip to the last chapter of the vehicle manual for the parts list. Changing the bulb yourself is quite simple—just buy a new one for about ten bucks, unscrew the base, and replace it. Just don't touch the glass with your hands, as the oil can cause it to fail prematurely. Dim lights can affect the visibility of the car behind you, so safety comes first—it's always right to deal with it promptly. If you're unsure, take a photo and post it on a car forum; there are plenty of helpful netizens who can help you identify it.
The Elantra's tail light bulb model is generally P21W for the brake light, but it's recommended to check the original manual for detailed specifications. Having driven for many years, I know you shouldn't carelessly choose the wrong bulb model. Safety is paramount - a non-functional tail light could lead to rear-end collisions, especially during night driving. Always check if the bulb is aged, water-damaged, or if the lens is cracked. When visiting auto parts stores, bring the old bulb for comparison to ensure compatibility. Note that models may differ between left/right sides and model years - there might be variations between 2012 and 2016 versions. Replacing it yourself isn't difficult, but wear gloves to prevent electric shocks. It's cost-effective and good practice.
