This page covers the 2017 Genesis G90 and helps you verify bulb sizes by lighting position, so you can match the correct replacement to the exact lamp on the car. The G90 uses LED lighting for many exterior and interior locations, and some headlight setups may differ by trim or market.
Use the bulb chart on this page as a position-by-position reference for items like the low beam, high beam, brake light, turn signals, license plate light, parking light, daytime running light, reverse light, side markers, and cabin lights. That makes it easier to confirm what fits before you buy a replacement.
Fitment on the 2017 Genesis G90 can vary by trim level, lighting package, body style, and market, so it is smart to compare the chart with the bulb already installed in your vehicle. Some versions use LED assemblies throughout, while others may have different headlight configurations, including a D1S-based option for certain headlight applications. If you are considering an aftermarket conversion, make sure the bulb, connector, and housing are compatible, and check whether the vehicle’s electronics expect an LED or HID-style setup. The safest approach is to inspect the installed bulb or assembly before ordering, especially for exterior lighting where packaging differences can affect fitment and function.
