- Replacement headlight bulb (H4 or H7, or LED, depending on your model)
- Small flat-head screwdriver
- Pliers
Steps:
1. Turn off the engine and allow the car to cool down if the engine has been running.
2. Open the hood of your Swift.
3. Locate the headlight assembly that contains the bulb you need to replace.
4. If there is a cap or cover protecting the bulb, remove it by turning it counterclockwise or by using the small flat-head screwdriver to pry it open.
5. Pull out the electrical connector from the back of the bulb.
6. Use the small flat-head screwdriver or pliers to remove the wire clip or spring that holds the bulb in place.
7. Once the clip is released, pull out the old bulb.
8. Insert the new bulb into the headlight housing, aligning the pins or tabs on the bulb with the corresponding slots in the housing.
9. Replace the wire clip or spring to secure the new bulb.
10. Reconnect the electrical connector.
11. Replace the cap or cover (if applicable) by turning it clockwise or by pressing it into place.
12. Repeat the process for the other headlight, if necessary.
13. Test the new bulb by turning on the headlights and checking if they work.
Note: If the new bulb doesn't work, make sure it's seated correctly and double-check that the electrical connector is securely connected. You can also try switching the bulbs between the headlights to rule out a faulty bulb or a problem with the headlight housing itself.
Before handling the bulb itself, wear gloves to avoid leaving fingerprints on the glass, as this can reduce light output and longevity of the bulb. Avoid touching the halogen bulb glass at all. If the bulb was touched inadvertently, clean it using rubbing alcohol and a cotton swab.
For LED bulbs, ensure that they are the right type and wattage for your vehicle, as some LED bulbs may have different orientations and cooling mechanisms compared to traditional halogen bulbs.
