Quick Answer
BMW E90 headlight assemblies (3 Series E90/E91, 2005โ2011) used Halogen (standard) and Bi-Xenon (optional) headlights, both with the signature “angel eye” rings. A 2008 LCI facelift updated the design, so pre-LCI (2005โ2008) and LCI (2008โ2011) units differ. Popular upgrades include halogen-to-xenon/LED angel-eye conversions and full LCI-style LED assemblies. Quality 1:1 aftermarket units fit plug-and-play at low cost โ match your build date and original light type, and code where a conversion requires it.
Introduction
The E90 is an enduringly popular car, and its original halogen angel-eye bulbs fade and yellow with age while the plastic lenses cloud from UV exposure. This guide explains the variants and the best upgrade paths.

Understanding the BMW E90 Headlight Variants
1. Halogen with Angel Eyes (standard)
Standard fitment. The angel-eye rings use small halogen bulbs that fade and burn out over time โ a very common complaint.
2. Bi-Xenon (optional)
Brighter xenon projector with auto-leveling. The xenon module can suffer corrosion with age and may need replacing along with the headlight.
3. Pre-LCI vs LCI (2008 facelift)
The 2008 LCI facelift revised the headlight design. Pre-LCI and LCI assemblies are not interchangeable, so identify your build date before ordering. Note the lens is not sold separately โ a damaged lens means replacing the assembly.
OEM vs Aftermarket: What to Know
OEM-grade aftermarket assemblies replicate factory fitment and beam pattern, and many offer upgraded LED angel eyes and projectors out of the box. Low-quality units risk beam scatter, moisture ingress and warning lights. Choose a verified factory source and code conversions where needed.
Fitment Checklist: Confirm Before Ordering

- Finish with a headlight aim check.

Frequently Asked Questions
Why are my angel eyes dim or yellow?
The original halogen angel-eye bulbs fade and burn out with age. Upgrading to LED angel-eye assemblies restores a bright, white ring.
Can I replace just the lens?
The factory lens is not sold separately, so a cracked or heavily clouded lens usually means replacing the full assembly.
Do conversions need coding?
A like-for-like replacement generally does not. Converting from halogen to xenon/LED may require coding to clear warnings.
