LED tail lamps?
do you guys know if there is a mod out there that lets you have 100% led tail lamps?
i was just wondering since i would prefer to have an actual flashing light rather than a pulsing glow from a lightbulb

an LED flash seems instantaneous
a light bulb takes an instant to heat up and to cool off and you can see it "pulsing" or glowing
compare:
mustang
Mustang One-Touch Turn Signal Kit (10-13 All) Review - YouTube
mercedes s-class
Mercedes Benz S-Class W221 Facelift Headlight Retrofit - YouTube
i think LED's give a much cleaner look

I have a mental image of you getting out of your car at every stop sign and red light, and asking your passenger to hit your brake pedal with a broom handle, while you feel queasy at the bulb filament slowly heating up, and then slowly cooling off after he releases the brake pedal. Every time the turn signal flashes, you dry heave.
Such a strange thing to be concerned about in life.

Yea the LED tail lights on S2's do light up quicker. Even the 2011 RX-8 brochure has a snippet about it:
"The RX-8's LED taillights light up quicker than incandescent bulbs to provide added visibility and safety."
I don't think S2 tail lights fit the S1 though...correct me if I'm wrong.

That may be true for household lighting or a controlled test environment but for automotive lighting it's easily verifiable even by the naked eye that LED tail lights light up quicker. I can record a video of the S2 RX8 later (since the middle light is incandescent versus the two main tail lights which are LED). But in the meantime, this thread has a video illustrating similar effects (in this case the two main tail lights are incandescent and the middle upper light is LED).

oh dont get me wrong, there is no denying that an LED's turnon is quicker than a more resistive filament bulb, but surely not enough to warrant investing in a (more than likely) costly solution to remedy something that only is recognized by people behind you that are driving around and looking to see who's taillights turn on in symmetry

The Michigan "WANKEL"
I remember Car & Driver doing a technical article on LED brake lights. They came to the conclusion that at higher speeds, at least, the difference in light-up speed can be significant in an emergency braking scenario (probably only if the driver behind isn't keeping adequate distance, but most drivers don't). Now, having said that, I wouldn't spend a ton of money converting my car to them if it didn't already have them, either.
