This page for the 2009 Lexus IS 250 helps you verify bulb sizes by lighting position, so you can match the correct replacement before you order. Because trim level, market, and lighting package can change the fitment, it is best to check the exact lamp location on your car and compare it with the bulb chart below.
For the 2009 Lexus IS 250, the chart includes exterior bulbs such as the high beam, low beam, fog light, turn signal, reverse, and side marker lamps, along with interior bulbs for the dome, map, courtesy, glove box, and trunk areas. Use the position-specific listings to narrow down the right bulb quickly and avoid buying the wrong part.
Fitment can vary on this Lexus depending on trim, body style, and whether the car has halogen or HID headlights. The low beam uses H11 on halogen-equipped cars and D4S on HID-equipped cars, while the fog light listing may also differ if the vehicle has been modified with LED or aftermarket housings. If your IS 250 has been converted from stock lighting, or if a previous owner installed non-OEM bulbs, always inspect the bulb already in the car before purchase and compare the base, connector, and size to the chart. That extra check is especially useful for front and rear turn signals, interior lights, and any aftermarket LED upgrades.
It depends on the headlight type. Halogen headlights use H11 low beam bulbs, while HID headlights use D4S low beam bulbs.
The high beam bulb is 9005.
The front fog light bulb is listed as 9006 LED, which may reflect an LED-style fitment or an optional lighting setup.
The front turn signal bulb is 7440A.
The rear turn signal bulb is also 7440A.
The back up reverse light bulb is 921.
The parking light bulb is 168. The front side marker bulb is 194NA, and the rear side marker bulb is also 194NA.
Interior bulb listings include 168 for the map light and interior door light, 194 for the courtesy light, DE3021 for the dome light, DE3022 for the trunk or cargo area light, and 37 for the glove box light.
Yes. Trim, lighting package, market, and body style can affect bulb fitment, so it is important to confirm the exact lamp position on your vehicle.
Check the headlight housing and the bulb already installed. A halogen setup uses H11 low beams, while an HID setup uses D4S low beams.
Use the chart as a starting point, but verify the installed bulb first. Aftermarket LED conversions can change the bulb type, connector, or housing compatibility.
Match the bulb by position, confirm the base and connector, and replace one bulb at a time when possible. For exterior lights, test the new bulb after installation to make sure it works correctly.
