LEDs are not "colder color temperature". 5000K is basically the color temperature of sunlight - which the human eye is optimized for. Cold color temperature is yellow (3,000K), white is sunlight (5,000K) and around 6,000K it starts turning some blue, then purple way up around 8,000-10,000K.
If car manufacturers didn't want people using fog lights together with the low beams, then they wouldn't allow both to be on at the same time. I can say there are tons of vehicles running around on the roads that blind people way more than a couple of 42W halogen bulbs shining down low at the ground with a little bit of scatter above the cut-off line. In the 15 years I've drove this truck at night, I have had ZERO on-coming cars flash their high beams at me signaling to me that they thought my lights were too bright - even with the fog lights on. The fog lights help fill in a lot of the road between the headlight cut off the the front of the truck, and also light the side of the road better than the headlight alone. They aren't really just for fog IMO.
I'm sure you really enjoy some of the new HID headlights ... talk about some of those being over whelming.
I could go wild and put in some 20,000 lumen low beams and really blind people.
I drive this truck, not you ... so I will make the lighting a little better if I can without spending a fortune because I want some better visibility on dark roads.
Edit - If the adjustable blade type LEDs I ordered from Amazon don't have a decent cut-off and scatter light all over, they will be sent back. I don't like being blinded on the road any more than anyone else, so I'm not going to do something to make people flash their high beams at me all the time. I'm pretty aware of how I could impact people.
