Is it illegal to modify headlights?

[LaColton]

Modifying car lights can be legal or illegal. Here is an introduction to car headlights: 1. Car headlights: Also known as car front lights or car LED daytime running lights, as the eyes of a car, they are not only related to the external image of a car owner but also closely linked to safe driving at night or in bad weather conditions. The use and maintenance of car lights should not be overlooked. 2. Modification methods: Increasing power or adding spotlights is a low-cost method, but the effect is limited. Replacing a 50W headlight with a 100W one will not simply double the brightness but only increase it slightly. Due to the mismatch between the circuit and the use of a 100W bulb, the loss in the circuit increases accordingly, the voltage at both ends of the headlight will drop, leading to an increased load on the circuit and potential safety hazards.
