Ok, so it was actually a few days ago but still. I changed my headlights out for whiter bulbs made by GP Thunder to see if I could tell a big difference or not and in the end I'm very happy and it is a much bigger difference than I'd even hoped for. The kicker in all of this? I paid under $20 shipped! I also got foglight bulbs to match but could not get them changed in the dark and it has rained and been a mess for days so hopefully I can get them done this weekend.
I took some photos but it is really hard to take photos of lights and get the color accurate I found. I ended up getting the rear of the car in the shots where I have changed out my license plate bulbs for LEDs and they are as white as white can be. Then the camera seems to balance the white colors better and the shots came out better. Also as a note the wall these are shining on is painted beige, so after photos are whiter light, but one a beige background. Still looks pretty good to me anyway. I took two before and two after, here they are:
And here are the headlights with my 400 lumen Cree LED flashlight to show white light, by the yellower headlights/foglights:
After, with the headlights changed, but the foglights are still the original:
These are extremely white in color in person, the whitest halogen lights I have personally used. For under $25 for headlights and foglights (once I get them installed) I am super happy! Why they do not use these color bulbs from the factory I'll never know.
I ordered from GP Thunder directly as they had the best prices, but they were available on Amazon too. So far so good, and I found this brand on BMW forums talking about getting whiter bulbs for the angel eyes on some models. I went with the 7500k version as the others will start to go bluish they say. Hope the photos help some people out.
