I have tried them and way brighter and white but..... seem to have my high beam dash light on dim while the lights are on low beam. Is there any worries about this causing other problems?

That is because the fog light circuit grounds through the high beams. It's designed to ensure that the fog lights go off when the high beams are used because the law only allows four forward facing main white lights (low beams + high beams + fogs equals six lights). The LED bulbs don't provide the resistance that the filament of an incandescent or halogen bulb does, so there will be some current back-feed. It has nothing to do with the brand or model of LED bulbs - just the fact that they are LED.

Now this is not to mention that fog lights aren't supposed to be really bright in the first place (that's not their function) and the factory "fog lights" are just decorative (non-functional) so you are probably blinding most everyone else on the road. A true fog light has a flat beam pattern with a sharp cutoff top edge so that it cuts under inclement weather to allow you to see the road in front of your vehicle. The decorative toy factory fog lights have no such pattern and just throw light everywhere.

Unrelated to the thread topic, but this seems like a good time to ask a related question:

Why is it that, in factory configuration, the low beams also cut off when the high beams are used? If four are allowed, why did the factory limit us to just two in this application? My daily driver (2010 Malibu) retains the low beam function when the high beams are in use (which is great for flooding an empty country road with light), but my '98, '99 and '02 Camaros did/do not retain low beam function when the high beams are activated.

That's a good question, especially since the Firebird doesn't have that issue... its low beams remain on when using the high beams (the fog lights still turn off). I don't know why the two have different headlight wiring.

6500K is BLUE.
BLUE light does not work well at illuminating wet streets.

I was using these in the low beam lights not fog. I removed them until I find that they wont cause any other electrical issues with the car.

Unlike Firebirds, the high beam and low beam circuits in Camaros don't share any common connection other than grounds, so there should be no way that the high beam indicator should be affected by whatever low beam bulb you might use. Have you made any other modifications to the lighting? Have you installed LED bulbs anywhere else? Have you checked the two primary lighting grounds on each side of the upper radiator support?

Not harmful, just feedback from the LEDs. Add a decoder or resistor to fix the dash light.

"feedback" from LED bulbs? Sorry, no such thing... LEDs do not create feedback. In some cases of a bad ground in a circuit, electrical current may "back feed" through a bulb (LED or incandescent) for an alternative ground but the low beam lights and the high beam indicator light are not even on the same circuit. The fog lights and the high beam indicator light are on the same circuit because it is designed to turn off the fog lights when the high beams are in use, so there could be some back feed there, but that is unrelated to the low beam headlights.

Very Strange, When I had the LED bulbs in for my low beams the brights indicator light on the dash would shine very dim with the low beams on. As soon as I changed back to the Halogen bulbs the light went out. I probably will stick w the Halo bulbs for now.
