They fit the 2015 Subaru XV, so they fit the Impreza too. I used them to replace the dome light and map reading lights (3 total). They give off a very white light and are brighter than factory bulbs. The brightness is good when you open the door to get in the car, but be aware that you might be annoyed by the brightness when using the map light while driving. I rarely use the car at night so the cover has hardly been used (except to open the door). I had a spare as I bought 4 and used 3 and I hope it was the only one. One star less because it spoils so quickly despite hardly being used. If the other one goes bad soon, I'll do that one star. One last thing I should have mentioned is that the heatsinks on it get very hot. So be careful if you touch them while they're on for a while. It doesn't flash every time you turn it on, but it flashes anyway. The funny thing is, whenever I need to turn on the lights in the car, I use the map light on the passenger side because on the driver's side it seems like it's shining in my eyes. The light that started to flicker now has the lowest "mileage". So I believe some of them are buggy and they start flickering. The problem is that the bulbs on the map are very difficult to replace. I will order 2 more and hope to get at least 1 good one out of them. The dome light I replaced 6 months ago is still working perfectly. Since I decided to give it another try, I'm leaving the rating at 3 stars. They are very bright, but I don't want to disassemble and change the headlights. So I changed my rating to 1 star due to short lifespan. I bought these Philips X-tremeVision LED 6000K 30mm Indoor String Lights (1 pack) and they are not that bright but they are 6000K and should last for years.
