Most of the LEDs that are mass produced in China are pure red, but you may be able to find a few red orange ones out there.


I agree.  LED technology has come quite a long way in the past couple years.  I'm a vendor on S2ki for LEDs, so I've had my fair share of terrible LED manufacturers and experimenting with LEDs. 

Currently building a set of turn signal / DRL LEDs from scratch with around 100 LEDs.


Edit:

An interesting tidbit I found.

While personal preference can play somewhat of a role in determining  that, red-orange is the unofficial industry standard for brake lamp  illumination color.   this is because the color appears brighter to the  human eye without actually being any brighter then a typical red led.   how can that be?


the easiest way to see that is to look at a human eye sensitivity chart:
