Hyundai Azera Headlight Bulb Size

Hyundai Azera headlight bulbs utilize H7, D1S, and H11B sizes depending on beam type and model configuration, with the high beam requiring an H7 bulb size and low beam accommodating H7, D1S, or H11B specifications. The replacement chart covers 2006 through 2017 production years with corresponding bulb size data.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The H7 bulb is the most prevalent type across the Hyundai Azera's headlight specifications, appearing in both high beam and low beam positions across multiple model years. It is a single-filament halogen bulb rated at 55 watts, operating on a PX26d base, and is widely used in European and Asian vehicle applications.
The Hyundai Azera uses the H7 bulb for the high beam headlight across all documented model years, spanning 2006-2017 without variation in that position.
For the low beam headlight, the 2012-2017 Azera models with halogen capsule headlamps use the H7 bulb, while those equipped with HID headlamps use the D1S bulb. These two bulb types are not interchangeable, as they operate on fundamentally different technologies and electrical systems.
The D1S is a high-intensity discharge bulb that requires a ballast to regulate its high-voltage arc. It operates at approximately 35 watts but produces significantly more light output than a comparable halogen bulb. Its use in the Azera is tied exclusively to the HID headlamp configuration.
The H11B bulb is specified for the low beam headlight on the 2008-2010 Azera. Although the H11B is visually similar to the standard H11, its retaining tabs are positioned differently, making it incompatible with standard H11 sockets. Substituting an H11 for an H11B in these applications is not supported by the specifications.
The 2007 Azera has two distinct low beam specifications depending on production timing. Early model units use the H7 bulb, while late model units use the H11B. This mid-year change means that the production date of a specific vehicle determines which bulb applies.
The 2011 Azera low beam returns to the H7 bulb after the H11B was used in 2008-2010, reflecting a change in headlamp assembly design between those model years.
Because the 2012-2017 Azera low beam position accommodates either H7 or D1S depending on the headlamp system installed, confirming the specific headlamp type on a given vehicle is necessary before selecting a replacement bulb for that position.
