997TT LED indicators go for around $800 for the pair. No one but the dealer sells them. I looked. Then you still need to swap out all of the amber LEDs to cool white LUXEON LUMILEDS. Honestly after going through this process either go with Techart LEDs or a great alternative Pre-Modded 997TT White LEDs like VividRacing sells (much easier, less time consuming, and cost about the same). The last part I've had to work out is a custom resistor box to keep the lights on without blowing them out. Don't forget labor guys.

 

Don't the 997 LEDs have both white and yellow already?

 

Only yellow (longer portion) for the turn signal. The parking light bulb is a standard type bulb.

 

I put the LEDs on my 997 Carrera. I ordered them on line (about $500). They were full housing replacements for the stock lights. They have amber turn LED's and bright white running lights. They make my 05 997 look 3 years newer and provide a great visibility factor for other drivers. I don't see how they could be modified to fit my 996TT. BTW: they had to be wired so they came on with the ignition instead of the headlight switch. Still looking for a simpler way to go for the 996.

 

..and can be used as led's ( white ) or orange ( turn ) w/out mod. seems perfect to me? i thinlk they're philips? but pls don't quoute me

 

I've used these on a friend's car a few months back. Pretty bright
