ok, not yet tested
I received 8 leds as ordered and 2 other leds which I didn't order. Doesn't exactly match the product description. Nevertheless the leds are bright. I do not know whether they have canbus errors as I've fitted only one led in the trunk with no canbus check.
1 received 10 pieces as ordered! And 2 leds for free. Thanks seller! My bad I gave 3 stars.
