Buick LaCrosse front light bulbs burned out again after replacement within 10 months on Buick LaCrosse

Some Buick LaCrosse owners report experiencing frequent burnout of front light bulbs shortly after replacement, which may be attributed to several factors. These include incorrect installation of the bulbs, which can lead to premature failure, and a depressed socket tab that results in poor contact, causing bulbs to burn out quickly. Additionally, if bulbs are burning out in different sockets, it may indicate deeper electrical issues. Using the wrong type of bulb is another common cause of premature burnout. Excessive vibrations can also damage the filament, leading to failure, while high power supply voltage can exacerbate the problem by causing bulbs to burn out rapidly. To resolve these issues, owners are advised to check the installation, ensure proper contact with the socket tab, verify the type of bulb used, and investigate any underlying electrical problems.
