These instructions apply to the Suzuki Alto Mk7 (GF) 2009-2014.

Headlight bulbs on the Suzuki Alto (2009-2014) are reached from behind the headlight in the engine bay. Handle the bulb by its base only.
Replace the bulb
- Open the hood and find the rear of the headlight unit.
- Unclip the round rubber dust cap on the back of the headlight.
- Unplug the connector, release the wire retaining clip and withdraw the bulb.
- Fit the new bulb – commonly an H4 (combined low/high beam); confirm against the old bulb – without touching the glass.
- Refit the clip, dust cap and connector, and test the light.
If you touch the glass, wipe it with alcohol – skin oil shortens bulb life. Replace in pairs so both sides match.
Frequently asked questions
What bulb does the Alto use? The main headlight is usually an H4; sidelights and indicators are separate bulbs. Check the handbook or the old bulb before buying.
