Toyota Prius C Headlight Assemblys

Toyota Prius C Headlight assemblys

Starting at $233.95, AutoBuffy stocks 12 headlight assemblies for the Toyota Prius C from trusted brands including TYC. A headlight assembly houses the bulb, reflector, and lens in one unit, projecting light onto the road ahead. When it cracks, fogs, or fails electrically, visibility drops sharply — a safety and legal risk you should not ignore.

Signs your Toyota Prius C needs a new headlight assembly

  • One or both headlights are completely dark even after replacing the bulb
  • The lens housing is cracked, chipped, or has moisture and condensation trapped inside
  • The lens surface is severely yellowed or oxidized and cannot be restored by polishing
  • The headlight beam pattern is uneven, scattered, or aimed incorrectly due to a damaged reflector
  • The assembly rattles or sits visibly loose because mounting tabs or adjusters are broken
  • Water is pooling inside the housing after rain or a car wash, corroding the socket or bulb

Which headlight assembly should you buy for your Toyota Prius C?

The main decision is whether to match OEM fit and output exactly or upgrade to a higher-output or styled alternative. You also need to choose the correct side — driver or passenger — and confirm whether your Toyota Prius C uses a projector-style or reflector-style housing, as the two are not interchangeable.

On most Toyota Prius C configurations, the headlight assembly is secured by a small number of bolts along the top and inner edge, accessible once you open the hood. Disconnect the wiring harness and any DRL or turn-signal connectors before pulling the unit forward. After seating the new assembly and reconnecting all plugs, verify the beam aim against a flat wall before driving at night.

Frequently asked questions

How much does it cost to replace headlight assemblies on a Toyota Prius C?
Parts start at $233.95 for a single headlight assembly on the Toyota Prius C. Labor typically adds one to two hours of shop time if you use a mechanic. DIY installation is straightforward on most vehicles, making this one of the easier repairs to save on labor without sacrificing quality.
Can I replace just one headlight assembly on my Toyota Prius C, or do I need to replace both?
You can replace a single side, and that is the minimum required fix. However, replacing both at the same time is worth considering if the other assembly is heavily oxidized, has matching age-related wear, or uses an older bulb type — mismatched housings can produce uneven light output and an inconsistent appearance.
Will an aftermarket headlight assembly fit my Toyota Prius C as well as the original?
Quality aftermarket assemblies are engineered to match OEM mounting points and wiring connectors for the Toyota Prius C, so fit is generally direct. Confirm the assembly specifies compatibility with your exact 2012–2019 production range, as mid-cycle refreshes sometimes change headlight design. Check that adjustment screws align with your Toyota Prius C's aim hardware.
How do I stop condensation from building up inside my Toyota Prius C's new headlight assembly?
New assemblies include sealed vents designed to let air equalize pressure without letting water in. Make sure the rubber dust boot behind the bulb is fully seated and any vent tubes are unobstructed. Persistent internal moisture after correct installation usually points to a cracked housing seal and warrants a warranty exchange.
Do I need to re-aim the headlights after replacing the assembly on my Toyota Prius C?
Yes. Any time a headlight assembly is removed and reinstalled, the aim should be checked and adjusted. Beam aim shifts slightly during the swap even when mounting hardware is returned to the same position. Most Toyota Prius C assemblies have vertical and horizontal adjustment screws accessible from the engine bay — a wall test confirms correct aim before driving.
How long does a replacement headlight assembly last on a Toyota Prius C?
A quality replacement assembly on the Toyota Prius C should last many years under normal conditions. Lens longevity depends heavily on UV exposure — vehicles parked outdoors in sunny climates yellow faster. Applying a UV-protective clear coat or lens sealant after installation significantly extends clarity and delays the oxidation that reduces light output over time.
