These SMD's are really super bright and shine well and work without problems. Since some customers think the do not I have a real tip times the back of the blister to read, because there is large and in German (without spelling errors) If the light does not go polarity swap, ie rotate the lamp 180 ° because LEDs of all types have only one! functioning passage direction. I read again and again, no good or not at the first light only. So informed, read or not at first switch to LED, and thus suppress the vote. MfG Rabis
