Hi all. Anyone know if a U.S. spec 997.2 with red rear turn signals can be converted to amber turn signals without changing out the whole tail light assembly? I've got a 2011 997.2 that I'm registering in France, but to complete the registration I need to change the rear turn signals from red to amber. My local dealer checked and said that the part numbers were the same for a U.S. spec tail light assembly (red lights) and a Euro spec tail light assembly (with amber lights). It may be possible to do some type of software update to the car, but the dealer doesn't have anything definitive for me as of yet (only a week since I started asking them). I've learned a lot about LEDs while researching this, and it seems that if you increase the current to an LED in the 600nm wavelength range, it will emit a shorter wavelength (585nm is amber, 580 is yellow)...so it seems technically feasible to have a software modification to do this. The other lower cost option is to replace the individual LEDs in the existing light assemblies. Thoughts?

 

Update: I don't know how thoroughly my local Porsche dealership researched this, but they told me that it was not possible to change the color of the LEDs in the tail lights with a software change. I opened up the tail light assembly and it is pretty complicated, with a printed circuit board and lots of miniature electronic components, so I opted to replace the entire tail light assembly. I found a source in Germany with original Porsche parts that was 50-60% of the cost of the parts from the dealer. I will also have to replace the 6-pin connector on the wiring harness to fit the European-spec tail lights, which looks to be a very simple job. My local Porsche dealership wanted 30 euros for the two connectors (left and right tail lights) and 105 euros (their hourly rate) to swap out the connectors, but they were out of stock so I found one at the local VW dealership for 12 euros for two. I'll change the connectors myself. The original Porsche connector is actually stamped with "VW / Audi" on it, so I'm getting an original part anyway.

I still think this could be done without replacing the entire tail light assemblies if I knew enough about the electronics (by replacing a driver or other component), but for expediency I am going down the path of infinitely less resistance.
