^This is correct. The switchback resistors are designed to slow down the turn signals. Without them, they'll blink very fast. It's a very simple install and we can help you through it if you have any questions! Just feel free to give my CS team a call and they'll gladly help out out.
Thanks alot. I see now that it's clearly stated that they come with the resistors. I need to quit reading parts descriptions when I have the kids by myself. I have trouble absorbing information when a 3 yr old is questioning your every action. Lol
