Your 2013 Lexus ES350 Headlight Setup
The 2013 model year brought a complete redesign of the Lexus ES — the sixth generation introduced the now-iconic spindle grille and a sleeker headlight design with integrated LED daytime running lights. The 2013 Lexus ES350 headlight bulb size is D4S HID for the low beam projectors and 9005 for the high beams, with H11 fog light bulbs. Factory HID low beams were standard equipment, paired with LED DRLs that gave the front end a distinctly modern signature.
The D4S projectors in the 2013 ES350 produce a clean, focused beam with a sharp cutoff line that prevents oncoming glare. As these bulbs age, though, you'll notice the output becoming dimmer and the color shifting away from pure white. Since the ES350 already has LED DRLs, many owners want their low beams to match that same crisp white tone — which is where an LED conversion or fresh HID bulbs come in.
Best Headlight Upgrade for the 2013 Lexus ES350
With factory HID projectors already in place, the 2013 ES350 is ready for either an LED conversion or HID bulb replacement — no housing changes needed.
Converting to LED makes particular sense on the 2013 ES350 because the car already has LED DRLs. Matching the low beams to the same white tone as the DRLs creates a cohesive, modern front-end appearance that looks factory-intentional. LED conversion kits for D4S housings replace the xenon bulb and ballast with a single module that delivers instant-on 6000K white light and won't degrade over time.
If you prefer the proven HID route, a fresh pair of D4S bulbs restores the original brightness in minutes. This is especially appealing if your current ballasts are still working reliably — just swap the bulbs and go. HID Nation offers D4S options from warm 4300K to cool 6000K so you can dial in exactly the color temperature you want.
The 2013 ES350 does use electrical monitoring, so a CANBUS-compatible LED kit or decoder is recommended to prevent any dashboard warnings. HID Nation includes a lifetime warranty and free shipping with every kit.
Frequently Asked Questions
What is the 2013 Lexus ES350 headlight bulb size?
The 2013 Lexus ES350 uses D4S HID bulbs for the low beam projectors and 9005 bulbs for the high beams. The fog lights use H11 bulbs. This generation of the ES350 came with factory HID headlights and LED daytime running lights as standard equipment across all trims.
How do I upgrade 2013 Lexus ES350 headlights to LED?
An HID-to-LED conversion kit replaces the factory D4S xenon bulb and ballast with a single LED module. Open the hood, access the back of the headlight housing, disconnect the ballast wiring, remove the D4S bulb, and install the LED unit in its place. The LED module connects to the same wiring harness. You'll likely need a CANBUS decoder to prevent dashboard warnings. The entire job takes about 30-45 minutes for both sides.
Will LED headlights match the LED DRLs on my 2013 ES350?
Yes — that's one of the best reasons to go LED on this particular vehicle. The factory LED daytime running lights produce a cool white tone, and a 6000K LED conversion kit for the low beams matches that color closely. The result is a uniform white appearance across the entire headlight assembly, day and night, rather than the warm-yellow vs. cool-white mismatch you get with aging HID bulbs next to LED DRLs.
What's the difference between D4S and D2S headlight bulbs?
The D4S bulb used in the 2013 ES350 is a mercury-free xenon design, while the older D2S contains mercury. They have different base connectors and are not interchangeable. The D4S was developed to meet environmental regulations while maintaining equivalent light output. When ordering replacement bulbs or LED conversion kits for your ES350, always confirm D4S compatibility.
How bright are the factory headlights on a 2013 Lexus ES350?
When new, the factory D4S HID low beams on the 2013 ES350 produce strong, well-focused light through the projector housings. However, HID bulbs lose output gradually — after several years, they may be operating at 60-70% of original intensity. If your headlights seem adequate but not as sharp as you remember, faded bulbs are likely the cause. Replacement HID or LED bulbs restore full brightness immediately.
