I've been reading a lot of threads about changing lights on the TL, however I am not sure which lights are the "switchbacks". Can you guys describe which lights they are? Or do a pic with an arrow pointing to the right ones. Thanks.

 

Switchbacks are use in the front lower signal,it basically will emit a white or slightly blue color for the parking lights but will switch to amber when you put on your signal.

This is what it looks like before the signal is switched,it comprises of a led bulb and a resistor to prevent hyper flashing when the signal is switched on




This thread has a lot of info

I don't think the switchbacks are LED when stock... I also think the stock bulbs are amber only no ?

 

Yes. Stock is amber or 1 color.
