Query: Not so bright than stock.

These lights are not brighter than stock white turn signal bulbs. Not to mention in turn signal (bulb housing) is covered in amber color. With stock white bulbs I can usually see the white bulb blink off of on coming signs from a distance at night. With these new bulbs you can't even seem them blink off reflectors from signs. However they happen to perform well and I'm not sure how long they will last.
