I just ordered the Cu Layer's Model 356 Led Tail Lights. I received a general email back thanking me for the order. In the email it said"If you have a replica 356 with modern lighting that employs an independent turn signal, this product will not work. " I have a Beck Speedster. Will these work for me? Also the email said they usually includes a free 12 volt flasher, however, they are out stock. Do I need the 12 volt flasher? For $225 I hope they work.
