Frequently Asked Questions
Are H4 bulbs still common?
Less common on new cars, but still widely used. Many popular used cars (older Fiestas, Civics, Swifts, Micras) use H4 bulbs.
Can I upgrade my H4 to LED?
E-marked H4 LED retrofits exist but the approved vehicle list is more limited than H7. Check the LED manufacturer’s compatibility list for your exact model.
How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
