How bulb compatibility works
Headlight bulbs are identified by more than appearance. The bulb designation, base or connector, housing application and lighting system matter.
Why designation matters
Different bulb families can have different mechanical and electrical characteristics.
LED and HID conversions
A physical fit does not automatically establish optical, electrical or legal compatibility.
Use the exact headlamp configuration
Some vehicles use different lighting arrangements for different trims or markets.
Safety
Headlamp performance affects visibility. Follow manufacturer installation guidance.
FAQs
Does a bulb that plugs in automatically work?
No. Optical, electrical and application compatibility still need verification.
Can this approve an LED retrofit?
No. It is a screening tool only.
