Why do the indicator bulbs in my Suzuki Alto keep blowing out?

I’ve been replacing the indicator bulbs on my Suzuki Alto more often than I should. Every few weeks, one of them blows out. Could this be related to a wiring issue o r something else? How can I diagnose and fix the issue to prevent further bulb failures?

Repeatedly blowing indicator bulbs in your Suzuki Alto can be caused by:

Voltage Issues: If the electrical system is supplying too much power to the indicator lights, it will cause the bulbs to blow. This could be due to a faulty alternator, voltage regulator, o r a short circuit.
Poor Wiring Connections: Loose o r corroded connections in the indicator circuit can cause electrical surges that damage the bulbs.
Using Incorrect Bulbs: Installing bulbs that do not match the manufacturer’s specifications can cause them to burn out faster.
How to fix it:

Check the alternator and voltage regulator for correct voltage output.
Inspect wiring: Look for any frayed, corroded, o r loose wires and replace them as needed.
Ensure you are using the correct bulb specifications as recommended by the manufacturer.
