Is it illegal to replace halogen headlights with LED?

[StJayce]

Yes, replacing halogen lights with LED lights is considered illegal modification. Halogen Lights: Also known as tungsten halogen bulbs or quartz bulbs, they are a variant of incandescent lamps. The principle involves injecting halogen gases such as iodine or bromine into the bulb. At high temperatures, the sublimated tungsten filament reacts chemically with the halogen. The cooled tungsten then re-solidifies on the filament, forming a balanced cycle that prevents the filament from breaking prematurely. As a result, halogen bulbs have a longer lifespan than incandescent bulbs. The power supply voltage for halogen lights is typically divided into AC 220V and DC 12V or 24V. LED Lights: An LED light consists of an electroluminescent semiconductor material chip, which is fixed to a bracket with silver or white adhesive. The chip is then connected to the circuit board with silver or gold wires, and the assembly is sealed with epoxy resin to protect the internal wiring. Finally, the housing is installed, making LED lights highly shock-resistant.
