Buy Lexus CT200h Headlight Bulbs

The Lexus CT200h uses a compact H11 headlamp bulb for both low-beam and high-beam duties across all 2011-2017 model years. Online fit-charts and service data confirm the shared size, 55-watt rating, and 12.8-volt operating voltage of this halogen light source. (AUXITO, SEALIGHT, PaulB Hardware) Frequent owner reports show that these lamps can dim or burn out sooner than expected, leading Lexus to extend coverage for early-build cars. (NHTSA) Because the CT200h employs projector housings, beam focus remains crisp when a fresh bulb is installed and correctly aimed. Upgrading to premium halogen, LED, or HID capsules can add brightness or a whiter color, yet drivers must stay within legal limits established by Federal Motor Vehicle Safety Standard 108.

H11 halogen bulbs draw 55 watts at 12.8 volts, producing roughly 1,300-1,400 lumens of clear white light. (Amazon) The filament sits inside a right-angle PGJ19-2 base that locks into the Lexus headlamp housing with a quarter-turn. Modern performance versions, like OSRAM's Night Breaker 220, claim up to 220 % more brightness and a beam up to 150 m long while still meeting DOT rules. (osram.com) LED retrofit options now pack compact drivers and cooling fans inside the base and can reach 6,000 K color temps for a crisp daylight look. (osram.com, Philips USA)

• Model years 2011-2017: Low-beam and high-beam = H11. (AUXITO)
• Fog lights: H11 sockets allow easy part sharing.
• Daytime running lights (DRL): Later CTs use built-in LEDs; owners note occasional strip dimming due to heat. (Lexus Owners Club)
• HID conversions: The projector design accepts D4-series HID capsules, which are mercury-free and safer for the environment. (SAE International)

Always confirm your exact trim in the owner's manual before ordering bulbs. (myportalcontent.lexus-europe.com)

• Flicker or pink hue-filament weakening or voltage drop. (ct200hforum.com)
• Intermittent shutdowns-loose connector or failing relay.
• One lamp dark, high beams ok-commonly a burnt low-beam bulb reported by many CT owners.

Replacing as a pair keeps light output balanced side-to-side.

1. Swap bulbs left ↔ right. If the problem moves, the bulb is bad.
2. Check 15 A headlight fuse in the engine bay box.
3. Inspect connector for corrosion.
4. Test system voltage (engine running, headlights on) should be 13.5-14.5 V.

If issues persist, inspect the switch or body control module.

A popular video guide shows the complete swap takes about 10 minutes per side with no special tools-just remove the rubber cover, twist the bulb counter-clockwise, unplug, then reverse. (YouTube)
Tips

• Wear gloves or use a tissue so oils don't shorten bulb life.
• Seat the O-ring fully to keep moisture out.
• After installation, re-aim the projectors to avoid glare. (NHTSA)

Repair-cost data show an average $84-$107 to replace one CT200h headlight bulb, with labor around $49-$72 and parts roughly $35. (RepairPal.com) Doing the work yourself saves labor, but be sure to realign the beam afterward.

• U.S. lighting law FMVSS 108 limits headlight glare and mandates DOT markings; several aftermarket LED H11 units have been recalled for exceeding these limits. (NHTSA, NHTSA)
• Aim angle must keep top cutoff below the rear window line of the car ahead to avoid dazzle.
• In Europe, ECE R112 sets similar photometric ranges.

• Replace in pairs every 2-3 years to maintain even brightness.
• Clean lenses with mild soap; hazy plastic scatters light.
• Avoid touching glass-fingerprints create hot spots that shorten life.
• Check alignment after long trips on rough roads.

Traditional HID capsules once relied on mercury to ignite the arc. Newer D4 bulbs-and all halogens and LEDs-are mercury-free, reducing hazardous-waste concerns. (SAE International) Always recycle spent bulbs at an approved facility.

By following the tips above, you'll keep your Lexus CT200h headlights clear, bright, and compliant-making every night drive safer and more comfortable.
