2016-2020 Subaru Impreza Light Bulb Size Upgrade Guide

Welcome to the ultimate upgrade guide for replacing all the OEM halogen bulbs on your 2017-2020 Subaru Impreza with LED light bulbs. This guide is only accurate for 2017, 2018, 2019, 2020 Subaru Impreza equipped with OEM halogen headlight bulbs. If your factory OEM bulbs are already LED type, it can't be modified or changed.

We dedicated the time and effort to put together all the OEM bulb sizes and LED bulb options in one easy to read location. The information below is free, and for our visitors. This list is an ongoing project and we reserve the right to make changes at anytime. Use the information below at your own risk. We provide zero warranties for the information we compiled. Why are we saying this? We definitely don’t mean to worry you. We say this because sometimes bulb sizes and kits can differ even within the same make, model, and year. The exact production month can sometimes make a difference in bulb sizes used. That makes it nearly impossible for us to be 100% certain the information below will be correct for your Sentra. We just want you to know there’s always that 1 percent chance it’s wrong, for your truck, for whatever rare reason. 

If you notice any changes that need to be made or additions that need to be included, feel free to let us know. It would be greatly appreciated. 

We hope you find it useful. Enjoy!
