These LEDs work in a 2025 Subaru Outback
I installed these LEDs in my 2025 Subaru Outback Touring XT on 12/10/25. They fit into the reverse light housing with plenty of clearance despite being 3/16โ to 1/4โ longer than the stock bulbs (I was worried about fit because I knew these were longer than the stock bulbs when I placed the order). Installation was about a five minute project; the only difficulty was the wires to the socket have very little extra play and the longer LEDs need more room to fit into the housing once they are plugged into the sockets. After installing the LEDs and writing this review, I saw a post suggesting that you remove the socket wires on a Subaru from a clip on the housing so you have additional play in the wires to help with the installation. The LEDs seem to fit tightly into the socket so I donโt think there will be a problem with the LEDs falling out of the socket. The light output is substantially brighter and whiter than the stock halogen bulbs. I also like the looks of these LEDs in the housing; there are no rear facing/projecting LEDโs, just an aluminum cap on the housing, so these LEDs blend seamlessly into the backup light and donโt detract from the looks of the lights. I donโt think this Subaru model has a โbackup light outโ warning but nothing lit up on the dash or chimed a warning after the installation of the LEDs so I donโt know if the CANBUS feature of these LEDs makes a difference. I learned something that you need to be careful about. To check polarity of the LEDs, I had my key fob in the car seat and I turned the ignition to on/run without starting the car. I then depressed the brake and put the transmission into reverse to check the lights. When I finished checking, I put the transmission into park, turned off the car and shut the door with the keys still on the passenger seat; the car locked with the key in the car!! Also, it wouldnโt unlock by pulling on the door handle. I had to use the other key fob to unlock the car. After looking at the settings that could have caused this to happen, it turns out that the car was set to lock/unlock when shifting into/out of Park; this caused the doors to lock and stay locked when I closed the door. I suggest you keep your fob in your pocket if you choose to test the LEDs the way I did. I canโt opine on the longevity of the LEDs since they have been in the car for 2 days. I will try to remember to update this review in six months or so. This is the first time I have used a Lasfit product so I am anxious to see how long these LEDs last. I have used GTS Lighting Carbide Series 2 LEDs in my 2018 Dodge Durango and those have lasted for 18 months without any issues. The Lasfits and the Carbide Series 2 look like twins so I am hopeful that the Lasfits are of similar quality.

So Bright!
The bulbs made. World of difference for me. I often get home after dark and being able to see my wife's black vehicle in the dark makes parking much easier.
