Subaru Legacy History

This mid-sized car was manufactured in 1989 and has 7 generations up to date. The earlier generations all were equipped with halogen reflector headlights like other vehicles, but the 4th generation launched in 2003 offered two factory options to the buyers: Halogen headlights or the Xenon headlights. 

The halogen H7 bulb with reflector lens offered average light, whereas the HID or Xenon came with a projector lens. With passing time, other options like LED were also available in high-end trims of the newer generations, and at last, in 2020, LEDs became the new normal, and all of the new Subaru Legacy cars will be fitted with LED headlights for both low and high beam.

If your Subaru Legacy is fitted with an HID Xenon headlight, you should check out your state’s laws to see because HID is illegal in many states. LED is a bit expensive, but it is better than traditional yellow halogens and overly bright Xenon lights.
