At first I was disappointed because the LEDs, not arrived as on the product picture in a nice cardboard box. They were chucked in a simple bubble letters in a plastic bag loosely. Well, I wanted to not install the box into the car. So wait if the LEDs are working ... On YouTube, there is a very nice video as you have to change the LEDs in the car. Goes right fix. BUT: there was a problem yet. The LEDs on the main interior lighting (ie in addition to the head on the top right) are too thick for the hole. You have the entire part dismantle (11 screws), then tuck the LED inside and it stuck on the other side of the plastic thread. Sounds indeed complicated, but is not so wild. It annoys only the fumbling. Another minus is that the indicator lights will appear as an error if well in the product description "no error" is. So this is not always true. But the message one can push away ...
Conclusion: in my model operate all LEDs. None was broken. And the new visual look of the interior is much better than the original lamps. Mission accomplished. For me, therefore, 5 stars.
