I've never heard of resistors being "in" the tails, as I've been told you have to wire them up front. However, I say screw resistors and their heat, and check this.
Here is a link to smoked tails I purchased some 2 weeks ago. They around maybe 2mm shorter than stock, but still fit perfectly. Note: You WILL have to take the bevel clasps off of the stock housings where they screw in, but you'll see what I mean. They look amazing, truly amazing. I am doing my camera work this next week after some plastidipping, so will be sure to link it in this thread if you haven't decided yet. Also note that a bulb for the reverse is not included, so get you an LED while you're at it!
Now, for your hyper flash. I have heard that not everyone experiences it for some reason. For the sake of time, I didn't care to test it, and I ordered
this nifty product off of Amazon.com at the same time as the lights. It will replace the flasher module under your dash, allowing for the negligible power draw from the LEDs. It is plug n' play, and gives a nice new blinker sound (not tick tock, more like thump thomp) that is lower in frequency and simply less loud. Works as it should.
You mentioned you wanted factory, and I insist that those LEDs look aweesome, awesome, awesome. They are lightly smoked, much more gray than black. However, if you are looking for no tint at all, still look for housings from that seller.
