2 stuks 30/45/60 cm auto LED-strip dagrijverlichting universele LED-strip buis LED-geleiderstrip

Goed licht na 6maanden gaat het lichtopbrengst wel achteruit

One of the bands does not light up white. I explained this to the support service and I am waiting for instructions. P.S. - I sent the proof of destruction of the product and I received the money in the account within 2-3 days.

I fixed the product in my car lights which were OK, but now the sticky tape to stick them on has started to come apart, haven't used with main car lights on yet, but I think they will become apart, tape not strong enough.

For me, only the first 4 LEDs on the strip work Does anyone have any idea if the tape broke or I didn't mount it properly? It is mounted according to the scheme, black to minus and yellow signal. Thank you in advance
