I found out how to swap out the OEM incandescent bulbs with plug and play LED bulbs. As you can see in the pics, the fog lights went from yellow to bright white. But, there is a problem with the cheap ones (about $25 for the pair) I used, lots of scattered light and glare. You can see a nice clean cut off line in the first pic with the tree with just the headlights, but when I turn the fog lights on in the second pic, their light goes well above the line. You can even see my shadow in the tree branches. I can imagine how annoying it would be for me to be following you with those puppies turned on. Or worse, how you would be blinded by them if you were in oncoming traffic.
I did not want to be "that guy" so I ordered some Phillips with a glare prevention LED crystal layout design. They should be here Friday and I plan to install them Saturday. I'll post pics so we can see if they are better at 4 times the price.
