What Causes Insufficient Brightness of Headlights?
1 Answers
Excluding the possibility of an aging battery, it may also be related to the headlight cover. The details are as follows: 1. Water vapor: If the owner replaces the bulb with a brighter one, it may affect the headlight cover, as a brighter bulb generates more heat. If the seal is not tight and water enters, the resulting water vapor will adhere to the inside of the headlight cover. After being exposed to high temperatures, the water vapor will evaporate completely onto the cover, making it appear yellow. 2. Automotive lighting: The water vapor produced will adhere to the inside of the headlight cover and, after high-temperature baking, will evaporate completely onto the cover, making it appear yellow and less bright. Automotive lighting can be divided into two categories based on purpose: illumination and auxiliary. Among these, only the headlights and some fog lights equipped on certain vehicles serve an illumination function, while the rest are auxiliary lights.
