Reinko Halogen Headlight Assemblies for 2015-2018 Ford Focus – Left & Right Pair, Plug-and-Play Sealed Housings

Reinko's pair of halogen headlight assemblies replaces both driver and passenger units on 2015–2018 Ford Focus models equipped with halogen headlamps.

If your Focus uses factory halogen headlights and you need a full replacement set, these plug-and-play assemblies are built to match the original fitment and mounting points. They come as a matched left and right pair with OE-style connectors and a sealed housing to keep out moisture and road debris. Read on to confirm compatibility, installation notes, and the practical benefits of swapping to a full replacement assembly rather than a bulb-only repair.

Will these headlights fit my 2015–2018 Ford Focus?

These assemblies are designed specifically for 2015–2018 Ford Focus models that came from the factory with halogen headlamps. They will not fit Focus models originally equipped with HID or LED daytime running lights, electric headlight systems, or other factory headlight variants.

• Compatible with: 2015–2018 Ford Focus with halogen headlamp only.
• Not compatible with factory HID or factory LED DRL models.
• Not for electric headlight or other non-halogen factory options.
• Interchange part numbers included for cross-reference with OE listings.

What’s included and how do I verify the parts match my vehicle?

The package contains one matched pair—driver side and passenger side headlight assemblies—so you can replace both sides simultaneously for consistent appearance and beam pattern. Use the provided interchange numbers to confirm match with your vehicle’s original components before ordering.

• Package includes: 1 pair of headlights (left and right).
• Interchange part numbers: Partslink Left FO2502339, Right FO2503339.
• Motorcraft references listed for easy dealer verification.
• Check your factory headlight type (halogen vs HID/LED) before purchase.

How durable and weatherproof are these assemblies?

The housings are sealed to prevent moisture ingress and protect internal components from rain, snow, and road contaminants. The sealed design helps maintain optical clarity and electrical integrity through typical driving conditions.

• Fully sealed construction to block water and dust.
• Designed to withstand common road conditions like rain and snow.
• OEM-style materials for reliable long-term performance.
• Proper installation preserves the seal and prevents fogging.

Are there any installation or bulb compatibility notes I should know?

These assemblies are intended for halogen bulbs; installing LED replacement bulbs may trigger vehicle error warnings or affect beam angle. If you convert to LED, use decoders or resistors as required and ensure bulbs are oriented correctly to maintain lawful beam pattern and avoid glare.

• Only fits halogen headlight models—LED/HID not supported without modification.
• LED bulbs can cause error messages; decoders may be necessary.
• When replacing bulbs, confirm correct bulb orientation to prevent improper beam angle.
• Contact support if you encounter fitment or alignment issues after installation.

Who is this for: These Reinko headlight assemblies are aimed at owners of 2015–2018 Ford Focus vehicles that originally came with halogen headlights and need a full, matched left-and-right replacement. They are a practical choice for drivers who want a like-for-like OE-style swap—especially those replacing fogged, cracked, or water-damaged housings—without upgrading to HID/LED systems. If you plan to retrofit non-halogen bulbs, be prepared for additional wiring or decoder components and to verify beam alignment after installation.
