What are the light bulb sizes for an ES300 Lexus?
There isn’t a single bulb size that covers every ES300. The exact sizes depend on the model year and the market (U.S., Europe, Japan, etc.). To be sure you have the correct bulbs, you should check your owner's manual, inspect the headlight housing, or use a parts lookup by year and VIN.
Why ES300 bulb sizes vary by year and market
Across the ES300’s production run, Lexus used different headlight assemblies, fog lights, and auxiliary bulbs depending on the trim level and regional specifications. As a result, the bulb codes and even the number of bulbs per side can differ from one car to another. The safest approach is to verify the exact configuration for your vehicle’s year and market before purchasing replacements.
Generation I ES300 (roughly 1992–1996)
Early ES300 models employed headlight and auxiliary lighting setups that varied by market. While some regions used more unified dual-beam designs and others used separate low/high beams, the exact bulb types were not identical across all cars in this generation. In practice, you should confirm by checking the specific housing or user manual for your vehicle.
Generation II ES300 (roughly 1997–2001)
Later ES300s continued to differ by market and trim. Some models used more common, widely available bulb formats, while others used slightly different configurations for fogs, parking lights, and turn signals. As with Generation I, the precise bulb sizes must be confirmed for your individual car.
How to find the exact bulb sizes for your ES300
The following steps help you identify the correct bulb sizes with minimal risk of error. Use one or more of these methods to confirm before buying replacements.
- Consult the owner’s manual. It typically lists the bulb type for each exterior light and sometimes includes a quick reference diagram.
- Check the headlight housing or bulb sockets. Some vehicles have size codes printed on the socket or inside the cover.
- Use a reputable parts or auto-parts retailer’s lookup tool. Enter the exact year, market, and trim, or use your VIN to pull the correct bulb sizes.
- Ask a Lexus dealer or certified service center. Provide your VIN and they can pull the precise bulb specification for your ES300.
Before listing, note that these steps are designed to ensure you match the exact bulbs for your car, which can vary by year and market.
After confirming the exact sizes, proceed with purchasing from a trusted source. Matching the correct bulb type is essential for optimal visibility, electrical compatibility, and safety.
