Plug and play
Worked on my 2018 Subaru limited that came with stock led headlights and halogen fog lights which always looked strange so I tried these and it was a direct replacement no extra steps took about 5 min total and has worked perfectly for months since and now looks great and is very bright without blinding my fellow drivers

Marsauto D2S LED bulbs
Installed on a 2008 Range Rover Sport HSE, replaced the original Xenon bulbs. It's not easy to find an LED bulb which actually fits and works on the Rover for a reasonable price. Definitely brighter, whiter, and casts a wider beam, so it's a good upgrade. I definitely like the idea that you can turn the bulb by hand after installation, so the beam pattern can be lined up properly (usually with the LEDs shining sideways), but has enough friction to hold it in place. With most other adjustable bulbs you have to remove the bulb and loosen some tiny screws and try it again. This is far more convenient. On the Rover the tricky part was what to do with the the Xenon igniter which is usually directly attached to the bulb, so for now it's tucked into the lamp housing cavity next to the bulb, and hopefully vibration does not cause any damage. Another concern is how long will these bulbs last, knowing that the cooling is relying on a small high RPM fan? Kept the original bulbs just in case, but for now these are great.

The bulb size is like almost perfect. The fit was a bit tight in my 2016 Kia Forte5 SX dome lights but I was able to get them in with very little effort. They're plenty bright however they're nothing special. I bought similar bulbs from a different brand and when I compared the new bulbs to the old bulbs they were basically identical even down to the PCB traces. Overall I have no real complaints. The price was good and I got enough bulbs to replace the ones I got if they ever fail. Only issues where that the fitment was slightly not perfect but nothing that stopped me from using the bulbs.
