For the 2015 Lexus IS 250, headlight bulb fitment varies by factory headlight configuration. The listed low-beam options are D4S and H11, while high-beam fitment includes D4S and 9005. Confirm the original bulb and headlight assembly before ordering, since these options are not interchangeable without matching the vehicle’s configuration.
Fog light fitment also depends on the headlight type: vehicles with halogen headlights use an H16 LED, while vehicles with HID headlights use an H11 LED. Other listed exterior bulbs include 7444NA for the front turn signal and parking light, 7440A for the rear turn signal, 921 for the reverse light, and 9005 for daytime running lights.
