Need to replace the damaged light in your Subaru WRX STI and are not certain which light fixture variety will match a housing? Many times, it occurs the recognized owner's guidebook (really the only legit supply of this sort of details) is out of reach or fails to include the necessary information for any particular modification. Apart from that, we now have observed often times that headlamps sizing may differ across Subaru WRX STI WRX STIs depending on the modification and year of manufacturing. So that we have compiled a great Subaru WRX STI light replacement information to ease the discomfort of looking for the correct light fixture kind and sizing for your interior or exterior lighting system.

Our Subaru WRX STI replacing chart retrieves the info from trusted bulb producers like Sylvania and Osram. On a single page, you can find out the OEM bulb sizing for your Subaru WRX STI headlights, fog lighting fixtures, tail lamps, turn signals, side markers, backup lights, braking system lamps, DRLs, dome lights, glove box lights, cargo area lights, and many others. In case, you would like to update the weakened halogen headlights of the Subaru WRX STI to a cool-looking LED or HID set we are here to recommend enough upgraded options with appropriate fitment for low beam and high beam headlamps.

To check that a headlight bulb is indeed bad, please follow these steps:

1. Make sure your headlight switch is turned to the "OFF" position and turn on the vehicle's parking lights (double-tap on the brake pedal or press the "Start" button twice), which will get activated only with the key out of the ignition. Now open and close any of your car doors, after which both headlights should be turned off again. If this did not happen, you need to check system fuses and replace them if necessary.

2. Turn on the parking lights again and leave them on for 5 minutes to warm up the headlight bulbs and ensure that any moisture evaporates from inside the headlight assembly. Do not turn on the headlights themselves as this might cause a sudden power surge which could damage your vehicle's electrical system.

Replace both of your 2019 Subaru WRX STI bulbs whenever one fails as they often fail within a few days of one another and by replacing just one you can avoid wasting money. The same applies to multi-bulb fixtures such as high and low-beam headlights, fog lights, or daytime running lights.
