Motorcycle with projector lens can pass the inspection. The motorcycle inspection line mainly checks the effectiveness of all lights and braking performance. As long as the headlight brightness meets the requirements, it is acceptable. Modifying the projector lens itself is not illegal. Article 49 of the Motor Vehicle Registration Regulations: Within three months before the expiration of the motor vehicle inspection period, the owner of the motor vehicle can apply for the inspection qualification mark at the local vehicle management office where the vehicle is registered. Before applying, the owner of the motor vehicle must handle any road traffic safety violations and accidents related to the vehicle. When applying: The owner of the motor vehicle shall fill out the application form and submit the vehicle license, compulsory insurance certificate for motor vehicle traffic accidents, tax payment or tax exemption certificate for vehicle and vessel tax, and the motor vehicle safety technical inspection qualification certificate. The vehicle management office shall confirm the motor vehicle within one day from the date of acceptance, review the submitted certificates and documents, and issue the inspection qualification mark.

I've been riding motorcycles for decades. Whether adding a lens can pass the annual inspection mainly depends on whether the installation is compliant. In China, motorcycle lighting must meet the 'Motor Vehicle Safety Technical Inspection Items and Methods' standard. The national regulations require that the focused beam brightness must not exceed the standard or the scattered light should not affect other drivers. If the lens modification uses OEM-spec LED or xenon lights, and the light pattern test meets the requirements after installation, it can pass the annual inspection in many places. However, if you modify it recklessly with excessively bright lights that dazzle others, the inspector will reject it outright or impose a fine. I once helped a friend modify his lens. He chose an anti-glare model from a reputable manufacturer and checked the parameters with the DMV in advance, passing the annual inspection in one go. In short, before modifying, don’t go for cheap options. Choose qualified products, keep the invoice and quality inspection certificate, and you’ll have evidence to appeal if any issues arise. This way, you can save a lot of trouble and stay safer.

I've worked in a motorcycle repair shop for many years and seen many customers ask if installing lens can pass vehicle inspection. The key lies in technical details: if the lens has good focus, stable brightness, and no modification to the circuit structure, it's usually fine. During the annual inspection, the inspector will use specialized equipment to test the headlight's focal point and light range—if it meets the standards, there's no issue. However, if the modification is non-compliant, such as misaligned positioning or overly bright blue-tinted lights, it will definitely fail, and some may even receive warnings or fines. I recommend buying lens products from reputable manufacturers and avoiding cheap online options that may pose short-circuit risks. For installation, it's best to go to a professional modification shop to avoid DIY mistakes. By the way, the benefit of lenses is enhanced nighttime visibility, but incorrect installation can increase accident risks—so balance cost and safety considerations carefully.

I'm in my early twenties and love tinkering with motorcycles. Installing a lens was to improve night riding. Last time, I fitted a lens headlight and was quite nervous before the annual inspection, but it passed smoothly—the inspector only checked if the brightness met standards. However, I've heard some friends failed due to non-compliant modifications and had to spend money to revert to factory lights. Cheap, low-quality lenses can overheat or have poor focus, definitely causing issues during inspection. From my experience, choosing a reliable brand and testing the lighting effect after proper installation can save a trip to the DMV and avoid wasting time and money. Now, I plan to double-check the parameters before the next inspection to ensure everything's in order.
