Need to swap the damaged light with your Subaru WRX STI instead of positive which light fixture type will fit into a socket? Many times, it happens that the established owner's guidebook (really the only legit method to obtain this kind of details) is out of reach or fails to have the needed data to get a distinct modification. Aside from that, we certainly have noticed many times that headlights dimension may differ across Subaru WRX STI WRX STIs dependant upon the modification and calendar year of production. So we have gathered a great Subaru WRX STI bulb replacement guide to relieve the pain of seeking out the right light fixture type and dimensions for that interior or exterior lighting system.

The type of you 2018 Subaru WRX STI bulb is also a factor that shows how often do you need to change your headlight. There are several different brands and styles on the market, but most can be divided into three types: halogen and xenon lights and LEDs. Generally speaking, halogen needs to be replaced most frequently while LEDs last the longest.

Halogen headlights, for example, aren’t supposed to last as long as xenon high-intensity-discharge lights, though the latter is far more expensive. Halogen bulbs are the most economical. They cost about $15 to $30 apiece and can last from one to three years if properly maintained. Halogens have a shorter lifespan than other types of lights, but they emit a bright white light that cuts through the darkness well enough for safe driving at night.

HID headlights, on the other hand, can last from five to ten years or longer because of their long-lasting quartz filament construction. HIDs also produce a more intense light with sharp cut-off features that reduce glare for oncoming traffic and increase visibility in heavy rain and snow conditions compared to halogen lamps which cause more reflection and glare for oncoming traffic.

On one website, you will discover the OEM light bulb dimension for the Subaru WRX STI front lights, fog lights, tail lamps, turn signals, side markers, backup lights, braking system lamps, DRLs, dome lights, glove box lights, cargo area lights, and many others.
