I ran them. I found out about them before they were released so I was able to get a good deal on a "Pre-Order."
I couldn't get the switchback to work however.
For the most part everything worked great except for one situation. If I drove with the parking lights on, the switchback would flash quickly. If I had no lights on or if I had my headlights on they worked perfectly. I attempted, albeit quickly, to add a resistor and it still occurred.
It was frustrating and I couldn't figure out how to bypass that issue.
I eventually took them out and replaced them with normal bulbs.
