Short answer:
Keeping your halogen headlight assemblies?
- Halogen - Philips H9
- HID - don't
- LED - don't
Upgrade the housings?
- OEM for best performance and reliability - 2021 LED units (recommend non-Pro/Limited)
- Morimoto XB - proper optics and DOT compliance but middling performance
- AlphaRex - just no, these are terrible re-branded Chinesium junk
- Got $$$? - go for a custom retrofit by BX, Kustom54, or other reputable shop.
