Can car halogen lights be changed to led lights? Is it illegal to change halogen lights to led lights?

Car halogen lamps can be changed to led lights, but it should be noted that the focus of the reflector and lens of the original halogen bulb of the vehicle is different from that of the led lamp; the light beam formed by the led lamp may not be so uniform According to the different levels of product quality, if the heat dissipation and constant current effects of LED lights are not good, the lighting effect will be relatively poor, and the heat dissipation of the lights is not handled well, which will also have a great impact on the vehicle itself.

It is not illegal to change the halogen lamp to LED, but if the LED lamp is replaced without a lens, the annual review cannot be passed; the requirements for the lighting in the annual review are in Chapter 8 Section 5 of the "Technical Conditions for Safety of Motor Vehicle Operation" Clearly: "The low beam of the headlamp should not be dazzling." As long as the xenon bulb is exposed or the LED headlamp has no lens, it is classified as unqualified.

In addition, after the halogen lamp is replaced with an LED lamp, no lens is installed, which will cause serious scattering. When driving at night, the light will dazzle the eyes of the opposing car owner, and the lighting effect is also extremely poor; so if you switch to an LED lamp, pay attention to the need to install lens.

The LED lights on the market have different lighting effects depending on their prices. The poor quality LED lights are actually similar to halogen lights, but they are slightly brighter and easy to flicker. The price is about 300; and the quality is slightly less. The brightness of a good led lamp can be equivalent to that of a halogen lamp of more than 200 watts, and the price will correspond to about 1,000.
