So I've been trying to find more information out about doing an LED upgrade on my halogen headlights, but I can't seem to find much about it. I have seen a couple of videos where people have done it, but I can't figure out why it seems to be so unpopular to do this upgrade. I went ahead and did all of my interior lights with LEDs from Diode Dynamics and now I want to complete the puzzle by doing the exterior lighting. Is there some problem with doing this to the stock halogens? If not, does anyone have any suggestions on which bulbs to use? From videos, I have seen one person using some bulb from alla lighting, but I don't know if there's any other options that I could go with. I also want to do my fogs, reverse, and license plate light if anyone has good suggestions on those as well.
