2.Light alarm prompt:When the "Please check headlights" prompt appears, it may be a bulb failure or circuit problem, which should be repaired in time.
3.Impact of OTA upgrade:Some car owners have reported that after the latest car system upgrade, the logic of automatic high beams is more conservative (the frequency of automatic turning on is reduced), which is a safety optimization.
4.Recommendations for winter use:It is recommended to turn off all lights after parking in severely cold areas to avoid over-discharge of the battery and failure to start.
5. New trends in lighting technology in 2023
According to recent industry trends, Buick will soon apply the following new technologies to 2024 models:
-Smart projector headlights:Navigation arrows and warning symbols can be projected on the road surface (already shown in concept car)
-V2X car networking lighting:Traffic information is transmitted between vehicles through light signals
-Adaptive color temperature adjustment:Automatically adjust the light color temperature according to weather conditions (yellow in rainy and foggy days, white in sunny days)
Proper use of vehicle lights can not only ensure driving safety, but also extend the life of the lamps. It is recommended that Buick owners check the lighting system every six months and replace aging bulbs in a timely manner.
