I have always disturbed the yellow light color of the normal parking light bulbs sitting yes in high beam reflector.
The Osram COOL BLUE have a really very white, almost a little bluish white. Not quite as cold / bluish as the retrofitted with me LED Daytime Running Lights in the bumper and a little whiter than the H7 Osram Night Breaker headlight in but it looks very nice.
The shelf life of Osram lamps I have always been convinced - I've never had a bad experience with it. While doing a review that their bulbs did not last long; I guess here often outside influences during transport are to blame and not the product itself.
Apart from the bulb in the tailgate with the license plate light I've never seen a renewed from me bulbs have to exchange a second time.
I buy, therefore, out of conviction for over 20 years only Osram or Philips !!!
The price differences for cheap villages are when all the effort for the exchange miteinberechnet but simply laughable and not worth mentioning.
So greed is often not permanently horny!
