They’re a great product but had to purchase a flasher unit to get the hyper flash to stop
the Led lights were easy to install and are working like a charm. I thought that these lights would be as bright as the old leds they aren’t. While that is ok I enjoyed the brighter less I had before. For the price my right is back up and looking good
