Are H11 and 9005 bulbs the same?
1 Answers
H11 bulbs and 9005 bulbs are not the same. H11 xenon bulbs are generally used in fog lights, and some models now use H11 for low beams; 9005, also known as HB3 bulbs, are mainly used for high beam lighting in car headlights. The following are the differences between bulb models and low beams vs. high beams: Bulb models: Bulb models include H1, H3, H7, H4, H11, 9005, 9006, H8, H9, H10. There are also some less common models, such as H13, 9004, 9007, etc. H13, 9004, and 9007 are single bulbs, while H9 has two filaments. H4 comes in two types: single xenon and H4 retractable bulbs. Differences between low beams and high beams: The intensity of light differs. Low beams are focused outside the focal point, emitting scattered light that illuminates a large area at close range. High beams are focused at the focal point, emitting parallel light with high brightness, capable of illuminating distant and high objects. The illumination distance varies. Low beams are designed for short-distance lighting with a limited range and non-adjustable focus. High beams are intended for long-distance lighting, offering a greater range and higher brightness. Usage scenarios differ. Low beams are used when driving on urban roads, where lighting conditions are generally good. Using high beams in such areas can easily dazzle oncoming vehicles and cause accidents. High beams are suitable for use on highways or in rural areas without streetlights to expand the field of vision.
