I've been looking for automotive T10 base LED bulbs that match HID bulbs of the headlights. There was a seller on ebay that sold those a few years back, but these days all I can find are 3500k, 5000k and 6000K, and 4100-4300k are nowhere to be found.

These bulbs are usually just plastic wedge bulbs with a bunch of 5050 LED chips. If I could find 4100-4300K 5050 chips, I'd go as far as even replacing them on the bulb myself.

Is there a way to change the color of lets say 6000k led chip to 4100k with filters?
