2014-2017 Acura RLX Jewel Eye Headlights: Recall, Moisture, and Replacement Guide

Understanding the Jewel Eye LED System

The front lamps on the 2014-2017 Acura RLX are a fully integrated LED system known as "Jewel Eye." This was advanced technology for its time and was standard on all RLX models. Unlike halogen or HID systems that use a single replaceable bulb, the Jewel Eye headlight is a complete, sealed assembly with multiple, non-serviceable LEDs. The outer three projectors serve as the low beams, while the inner two are added for the high beams. This multi-lens setup allows for a very wide and evenly distributed pattern of light, improving visibility on dark roads. The entire assembly includes the lenses, the internal projectors, the LED light sources, and the outer housing. An external LED control module, sometimes called a driver or ballast, provides the correct voltage to the LEDs and is typically mounted to the bottom or back of the headlight housing.

Known Issues and Symptoms of Failure

NHTSA Recall for Headlight Delamination (Dim Light Output)

The most significant known issue is NHTSA Safety Recall 14V792000 (Acura campaign JN2), which affects all 2014 and 2015 Acura RLX models. The problem involves the reflective aluminum film inside the headlight housing, which can peel away or "delaminate." This defect significantly reduces light output, diminishing visibility at night and increasing the risk of a crash. The cause was identified as a porous reflective film that allowed moisture to degrade the adhesive. The official remedy was for Acura dealers to replace both the left and right headlight assemblies free of charge with updated parts. When buying a used vehicle or replacement parts, it is crucial to verify if this recall has been completed.

Moisture and Condensation

Like many modern vented headlights, the RLX Jewel Eye units can be prone to moisture intrusion. While minor fogging that clears up on its own can be normal, excessive water droplets or persistent condensation points to a problem. This can be caused by a bad seal around the housing, a crack in the lens or body, or a missing cover on the back where the wiring connects. Trapped moisture not only looks bad but can also lead to corrosion of internal electronics and the failure of the LED driver module. If you see water pooling inside the light, the seal has failed and the assembly will likely need replacement.

Individual LED or Module Failure

Though LEDs are long-lasting, they can still fail. Symptoms include one or more of the individual "jewels" not lighting up, flickering, or a complete loss of the low or high beam function on one side. Often, the issue is not the LEDs themselves but the external LED control module (part number example: 33119-TY2-A012) that powers them. This module is a separate component bolted to the headlight assembly and can often be replaced independently without needing to replace the entire headlight. If your headlight is flickering or has gone out completely, diagnosing the control module first can save significant cost.

Buying a Used 2014-2017 RLX Headlight: What to Check

Given the high cost of new OEM headlights, a quality used OEM part is an excellent value. However, careful inspection is key.

• Check for Recall Compliance: Ask the seller if they know whether the headlight is a post-recall part. The updated parts for the delamination recall have the letter "O" in front of the ID code stamped on the assembly. Pre-recall parts should be avoided.
• Inspect the Lens: Look for deep scratches, hazing, or yellowing from UV damage. Check carefully for small stress cracks, especially around the edges. While minor surface issues can be polished, major damage cannot be repaired.
• Look for Signs of Moisture: Check the inside of the lens for dried water spots or a mineral deposit line. This is a clear sign the headlight had a leak in its past and should be avoided.
• Verify All Mounting Tabs: The plastic mounting tabs are brittle and often break during minor accidents or even improper removal. Inspect every tab to ensure it is intact and has not been repaired with glue or epoxy, which may not hold up.
• Confirm Part Numbers: There are several part number revisions. While they are generally interchangeable for the 2014-2017 model years, it's best practice to match the number on your old part. The right (passenger) side part numbers typically start with 33100-TY2- and the left (driver) side starts with 33150-TY2-.
• LED Control Module: Confirm whether the used assembly includes the LED control module. Sometimes they are sold separately, and you will need to either transfer your old one or purchase another.

Cost of Replacement

Replacing a Jewel Eye headlight can be expensive, especially from the dealer. This makes finding a quality used OEM part a significant cost-saving measure.

Note: Aftermarket headlights are available but may have inferior light output, beam pattern, and longevity compared to OEM units. For a complex system like the Jewel Eye, a used or remanufactured OEM part is often a more reliable choice.

Replacement and Aiming

Replacing the headlight assembly on a 2014-2017 RLX is a moderately difficult job because it requires the complete removal of the front bumper cover. 🎬 Watch this step-by-step video on removing the RLX bumper Once the bumper is off, the headlight is held in by several bolts. The electrical connectors must be disconnected before the assembly can be removed.

Headlight Aiming

Any time a headlight assembly is replaced, it must be properly aimed to ensure correct visibility and avoid glaring other drivers. This is done by parking the vehicle on a level surface about 25 feet from a flat wall. The headlights have vertical and sometimes horizontal adjustment screws. Turning these screws raises, lowers, or shifts the beam pattern. The goal is to have the brightest part of the low-beam cutoff line slightly below the center height of the headlight itself. The RLX also features an Auto High Beam system, which uses a camera to switch between high and low beams automatically. This system does not typically require calibration after a headlight replacement, but aiming is still mandatory.
