I have ordered these LEDs for my overhead lights in my Mazda 6 as the original bulbs W5W not ausleuchteten my ideas according to the interior. Since the originals only a few millimeters into the reflector stuck into it, I was looking for LEDs that are long enough and radiate in all directions. They saw in this picture a bit longer than the comparable competitors products and therefore a lot of the decision for this. An error message there is not with me, because I do not insets for outdoor lighting and my car also recognizes only those. My interior lighting dims when switching from dark to light and when switching from light to dark, this is a lot nicer in the glass base bulbs, because the LEDs turn on until a certain tension and then permit only a very short Dimmungsprozess. All in all, the lights very bright and light up the interior of uniform. The light color is resistant to the normal W5W bulbs naturally very white. The illustrated heat sink between the SMD-LEDs and the connector is in me skillful pears not available, a greater heat generation, I could, as expected, no notice. Having these LEDs now installed in the driver's area, I wanted to spoil me another 2 in the font, and also found on Amazon 20pcs for about 2 euros more than this here as soon as I get this, I report on the direct comparison.
