just briefly, I purchased a bunch of 12v festoon bulbs on ebay that are supposed to be white.
Last week I got the first set of 4 and they all appear dark blue inside my car, I told the seller and he has sent a new batch over, these are also blue.
Is it possible that the voltages in the interior dome light are not 12v? I am trying to figure out why he says they are supposed to be bright white and I get them in dark blue.
Are they blue when lit? I have some that are blue glass, and light up like fake HID bulbs (white w/bluish tint). 12V 10W are my bulbs, 12v 5W are stock.
He’s got his LED’s mixed up then. LED’s will always show the correct color down to a fraction of their design voltage, except white LEDs will get a purple tint when underpowered (and usually have a slight tint anyway)
