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.
