What bulbs are in Lexus IS200?

There isn't a single bulb specification for the IS200; it varies by year and market. The car uses different headlight, fog light, tail light, and interior bulb types depending on trim and region. This guide covers common configurations and how to verify the exact bulbs for your vehicle.


Common exterior lighting configurations


The following outlines typical setups you might encounter on an IS200, with notes on regional variations. Use this as a starting point and confirm with your manual or the bulb itself.



  • Headlights: Some IS200 models used a dual-filament halogen bulb in a traditional reflector housing (often referred to as H4/HB2). Other editions with projector-style headlights use dedicated low-beam and high-beam bulbs such as H7. In certain markets, HID (high-intensity discharge) headlamps were offered as an option or on higher trims.

  • Front fog lights: Commonly equipped with halogen bulbs, typically in the H11 or H3 family depending on trim and regional specifications.

  • Rear lighting (tail lights, brake lights, and turn signals): These assemblies generally use standard automotive bulbs, with the exact base types varying by year and market. Expect a mix of multi-filament or wedge-style bulbs depending on the component and year.


Conclusion: The exact exterior bulb types depend on the IS200’s year and market; verify by checking the bulb markings, the owner’s manual, or Lexus parts catalogs for your specific vehicle.


Interior and dashboard lighting


Interior illumination in the IS200 covers cabin lights, map lights, instrument panel backlighting, glovebox, and trunk courtesy lights. These use common wedge or festoon bulbs that are widely available, but exact codes vary by year and trim level.



  • Cabin and map lights: Typically wedge-type bulbs such as W5W (often labeled 194) or similar in various locations around the ceiling and doors.

  • Instrument cluster backlighting: Often miniature bulbs (such as T5 or related variants) configured for the dash, with numbers changing by year.

  • Glovebox and trunk lights: Usually wedge or festoon bulbs, again depending on the exact year and trim.


Conclusion: Interior lighting relies on standard, widely available bulb types, but the exact codes should be confirmed for your IS200’s year and region.


How to identify the exact bulb type for your IS200


To ensure you buy the correct bulbs, follow these steps:



  • Consult the owner’s manual or an official Lexus parts catalog for the exact bulb codes assigned to your year and market.

  • Inspect the existing bulbs: remove one and read the embossed code (for example, H4, H7, W5W, 194, etc.).

  • If in doubt, note the fixture (headlight, fog, tail light, interior) and search by year/region plus the fixture type to confirm compatibility.

  • When replacing headlights, consider replacing in pairs to maintain even brightness and color temperature.


Conclusion: The most reliable way to ensure a perfect fit is to verify the exact bulb code from the manual, the existing bulb, or an official parts database.


Summary


The Lexus IS200’s bulb configuration is not universal; it varies by year and market, especially for headlights and optional lighting upgrades. This article provides a framework to identify the likely bulb types and confirms how to verify exact part numbers for your vehicle. If you share the IS200’s model year and market, I can supply precise bulb codes for headlamps, fog lights, tail lights, and interior lighting tailored to your car.

What type of bulb is in my headlight?


To find your headlight bulb, check your vehicle's owner's manual, look for the bulb number printed on the old bulb or housing, or use an online vehicle bulb finder tool. The easiest methods are using an online tool by entering your car's year, make, and model, or by physically removing the old bulb to read the code printed on its side. 
Method 1: Consult your owner's manual

  • Your vehicle's owner's manual will have a section listing all the required bulb types and sizes for your car.
  • This is the most reliable method for ensuring you get the correct bulb, as it provides exact specifications. 

Method 2: Check the old bulb or headlight housing 
  • Carefully remove the old bulb from the headlight assembly. 
  • Look for a part number or bulb size code printed directly on the side of the bulb or on the plastic base. Common sizes include H7, H11, 9005, and 9006. 
  • Sometimes the number is also printed on the headlight housing itself. 

Method 3: Use an online bulb finder 
  • Many auto parts websites and bulb manufacturers have online tools. 
  • Simply enter your vehicle's year, make, and model, and the tool will show you compatible bulbs for your headlights and other lights. 

Tips
  • Dual-filament bulbs: Some cars use a single bulb for both low and high beams, while others use separate bulbs. The owner's manual or bulb finder will specify which is correct for your vehicle. 
  • Safety: Replacing your headlights promptly is important for road safety, especially since worn-out bulbs can dim, flicker, or fail. 
  • Consistency: Make sure to replace both headlights at the same time if they are old, as they are likely to be at similar stages of their lifespan.
