Not sure about the other states but in CA, red and blue are illegal (only law enforcement vehicles can run them).

So if tail lights are red, does the law state that you can only have red lights on the back of the car?

In CA you can run red or amber in the back and white or amber on the sides and the front. Red and blue are not allowed in the front.

it's not going to work. the only way to do that if you just bypass the relay altogether and wire it direct. as the trigger wires for the relay does not need a constant 12v to "trigger" the relay.

as for dimming the angels. you can just add more resistors to it to dim them down. but you'd probably have to know what you're doing i guess.

This sounds like a stupid question, but can you actually dim LED's? I thought that wasn't possible, or if so you would damage them...

yes you can. just put more resistors on the circuit and it will essentially dim the LEDs. that's what a rheostat is pretty much. it's like a variable resistor (well actually is).

maybe i'll get one later and wire it up for you guys to see. i will do it outside of the car though, too lazy to run it inside the car when i don't even want them.

One thing to be careful of, is to make sure the rheostat (potentiometer) is rated for the power (W). Although with LEDs it wont be much...

Has anyone done this that can provide a How-To? Also, if you insert a rheostat into the mix, will that prevent the fade on/off from working when you lock your car?

ive always found the dimness of the oem ones to look crappy but to each their own i guess

I'm getting an AE kit soon .. I wouldnt mind DIY'ing this:

Using a standard 12volt automotive relay, some connectors, wire, and a rheostat thats rated properly. (I dont want to guess the rating/resistance range. Would have to measure the circuit first and play with some resistors)

But it would be wired as such:
- When the relay is not powered, it provides power straight through to the AE as it does now (so fade on/off will still work)
- 12V Trigger input to the relay would be headlight low beam power
- When your headlights turn on, the relay switches- wired so it powers your AE's not with 12v, but 12v sent through a rheostat installed in the cabin, first.

When you turn on your lights, the brightness you adjust with the rhetrostat dial applies. When your lights are off, it will be powered straight through for full brightness.

This can obviously be varied to suit your desires but its not difficult for anyone to do.

Much easier than transistor switched circuits, anyway
