They are truly plug 'n play replacements to the original turn signals. Watch every video you can to see how to remove and disconnect everything. It is not necessary to disconnect the mirror but being able to set it aside makes the rest of the work much easier.
Keep the screws organized for the three parts you remove (frame, shell, lamp) as they are not the same. Use care with the plugs. One requires sliding back a red locking clip before the plug can be disconnected.
Why not 5 stars? The design of the new LED strip does not cast a sufficient amount of light to illuminate the end of the indicator, which sits inside the mirror frame, as does the original. So, you no longer see that indication that your signal is flashing. I've not yet replaced the passenger signal, undecided if the new look is worth the trade-off.
Dynamic LED Sequential Mirror Turn Signals for Audi A3/A4/A5/S4/S5/RS5/Q5/SQ5 - Smoked Lens
These signals are nice and look great. Good quality part and adds a subtle touch of flair. Highly recommend
Very cool effect, no instruction or tips to install. Was not easy to get mirror cover off/unclipped. Manufacturer should make an install video.
I installed them on my Rs5 and it looks great so much better than the factory. It took me awhile to change my first mirror cause the video I watch was for A4 /A3. But after the first mirror was done I knew what to do on the next one and it went better and quicker. Over all I love how it looks on my car.
