My Suzuki Every’s indicator bulbs keep blowing—what could be the cause?

I’ve replaced both left and right indicator bulbs more than once. They work for a few weeks o r months, then stop again. Could this be caused by fluctuating voltage, faulty wiring, o r a weak battery? How can I find the root cause?

Blinker o r indicator bulbs burning out repeatedly usually point to electrical o r vibration-related problems:

Weak o r Dirty Sockets: Loose contact causes arcing, which can damage the bulb.

Alternator Issues: Voltage spikes can overheat and blow bulbs.

Bumpy Roads & Vibration: Constant road vibration can break filament in the bulb.

Solution:
Use vibration-resistant bulbs, clean the indicator bulb sockets, and test your vehicle’s voltage output should be between 13.8–14.4V. If the flasher unit relay is malfunctioning, replace it to prevent overloading the circuit.
