What kind of headlight bulb for 2008 Hyundai i30?

The typical setup for a 2008 Hyundai i30 with standard halogen headlights is low-beam H7 and high-beam H1.

In practice, there can be regional or trim-based differences. Some vehicles may use non-halogen options (such as HID or projector systems) or different bulb configurations, so it’s important to verify the exact type for your specific car before buying replacement bulbs.

Common headlight bulb configuration on the 2008 i30

Below are the bulbs you’re most likely to encounter in the stock halogen setup. Use this list to confirm the bulb types in your car.

• Low beam bulb: H7 (12V, typically around 55W)


• High beam bulb: H1 (12V, typically around 55W)

With this common arrangement, you generally need two H7 bulbs for the low beams and two H1 bulbs for the high beams, one per headlamp side. If your car uses a different configuration, the replacements will be different and should be identified before purchase.

How to verify your specific bulb type

To confirm the exact bulb type in your vehicle, use these steps to inspect the headlight assembly and the bulb itself.

1. Turn off the engine and open the hood to access the headlight housing.


2. Remove the dust cap to reach the bulb.


3. Disconnect the wiring harness and, if present, unclip the retaining spring or lock.


4. Carefully remove the bulb and check the base marking on the bulb or the base (look for labels such as H7 or H1).


5. Match the base to a replacement bulb. If the markings indicate H7 (low beam) and H1 (high beam), you’ve got the common configuration; if not, note the exact base type and search accordingly.

If your headlights are HID (xenon) or use a projector/LED setup, you will not replace them with standard halogen bulbs. Those systems require different components or assemblies.

Replacement options and installation tips

For the standard halogen setup described above, replacements typically fall into these categories. Use this list to plan what to buy.

• Low beam replacements: H7 bulbs


• High beam replacements: H1 bulbs

Tips for buying and installing:
- Choose 12V bulbs with the correct wattage (usually 55W for both H7 and H1 in many setups).
- If upgrading for brightness, consider reputable brands (e.g., Philips, Osram) and note that higher-performance bulbs can run hotter and have different beam patterns.
- Avoid touching the glass with bare fingers, as oils can shorten bulb life. Use a clean tissue or gloves when handling bulbs.
- After installation, check alignment and adjust the headlight aim if needed to prevent glare for other drivers.

Regional/trim variants and where to check

Hyundai i30 models can differ by market, trim level, and optional equipment. Some regions offered HID or projector headlights that do not use standard halogen bulbs. If you’re unsure, consult your owner's manual, check the service label inside the hood, or contact a Hyundai dealer with your vehicle identification number (VIN) for an exact specification.

Summary

For a typical 2008 Hyundai i30 with standard halogen headlights, expect H7 low-beam bulbs and H1 high-beam bulbs. Always verify the exact bulb type on your specific car before purchasing replacements, especially if your vehicle has HID or projector headlights, or if you’re in a market with a different configuration. Proper handling and alignment are important for reliable lighting and safe driving.

How do I know what bulb to get for my headlight?

Every headlight is designated with a bulb size. For a bulb installed in your car, you can find the number stamped or printed on the side of the bulb. It's also listed in the service manual and in an auto bulb guide. Only the correct bulb size will fit in the headlamp housing and connect to the factory wiring.
