Can LED lights pass the vehicle inspection?

LED lights can pass the vehicle inspection. Here are some considerations regarding the installation of LED lights: 1. Whether to install a lens: Before installing LED headlights, first check if the halogen lights have a lens. If there is no lens, there are three solutions: one is to install LED bulbs with a 'built-in cutoff line function' for low beams, which can achieve a lens-like effect, creating a left-low and right-high light pattern to reduce glare for oncoming traffic. The second option is to directly install a lens when fitting LED headlights. The third is to use LED bulbs with good light-focusing performance. The specific choice depends on the vehicle model. 3. Check the original bulb model: Not all LED headlights can be installed in every car because the interface models vary, just like checking whether a household bulb is screw-type or bayonet-type. For example, the bulb model for both high and low beams of the old Lavida is H7, so purchasing LED headlights with an H7 model will suffice.
I think whether LED lights can pass the annual inspection largely depends on how they are installed. Last year, I retrofitted my car with LED headlights myself, and during the inspection, the technician used a light meter to measure them a few times. The brightness was too high and almost caused me to fail. Later, I had to pay to have a professional shop adjust the light angle to lower the intensity before it passed. Factory-installed LEDs usually don’t have issues, but aftermarket modifications depend on whether the light pattern meets standards—it shouldn’t be too scattered or cause glare, otherwise, it poses a safety hazard and will definitely fail. Nowadays, annual inspections are very strict in many places. To save trouble, I recommend not modifying lights recklessly. If you must modify them, choose products with brand certification, and after installation, test-drive a few times to check the effect. Also, pay extra attention to the lighting system during regular car maintenance to avoid trouble on the road.
Can LED headlights pass the vehicle annual inspection? As an experienced driver, I don't think it's absolute. First, it depends on whether they are factory-installed. If so, it's usually smooth sailing, but self-installed LED lights can cause many issues, such as excessive brightness or incorrect beam angles, which are checked during inspections. I once helped a friend with a modification, and the vehicle failed the inspection because the light dispersion affected other drivers' safety. My advice is to always refer to national standards for light intensity and distribution requirements before modifying headlights. It's best to have certified LED components professionally installed—don't skimp on quality by buying cheap products. Also, remember to regularly clean the headlight covers in daily driving, as dust buildup can affect performance. In short, safety comes first for a smooth inspection!
