The reading light of Lavida Plus is always on because the constant-on mode is activated. If the light does not turn off when adjusted to OFF, it indicates a malfunction in the rear interior light of the car, possibly due to a damaged switch. Halogen Reading Light: Halogen interior reading lights use halogen materials. Halogen-based interior reading lights are technologically mature and low-cost, making them widely used in many vehicle models. However, they also have some drawbacks, such as radiation, mercury content, and susceptibility to breakage, which can cause inconvenience during transportation and installation. Their service life is approximately 8,000 hours. LED Reading Light: LED interior reading lights use LED materials. LED-based interior reading lights are characterized by being pollution-free, radiation-free, and having a long service life, with a theoretical lifespan of over 50,000 hours. Many vehicle models have already been upgraded to LED interior reading lights. However, due to their higher cost, LED interior reading lights have a significant impact on general usage, especially in China, where the adoption rate is quite low. In developed countries, the adoption rate is much higher.
