Philips D3S-42V35W. Is modification supported: Modification is possible, but must comply with relevant standards. Advantages of modification: The headlights configured at the factory meet basic standards, but vary across different models. Due to production conditions and cost constraints, they only meet minimum requirements. Additionally, headlights may experience brightness degradation over time due to high temperatures and oxidation. Professional modification by certified shops ensures no safety hazards. Key considerations during modification include avoiding full headlight assembly replacement. For models like the KLZ with integrated high and low beams, simply replacing the H4 xenon bulb and ballast is sufficient. Proper modification requires a lens, bulb, and ballast—all three components are essential.
