These bulbs meet their primary function: illuminate correctly. Note that the color blue is not at all clear when lighted. The color of light tends towards white but it is far from pure white. This is still less than my original yellow bulbs. In this pack there are also 2 Blue Vision W5W bulbs. I advise you to use them to change your pilot if those you are already pretty yellow or it may settle a little. Remains to be seen how long they will last.
