Can LED lights pass the vehicle inspection?
2 Answers
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.
