When I first bought them, they we the only company I could find that made a dual revolution. I can only give input about their dual revolution, if I have ever used their regular lights I can't remember.
I replaced the top 5 with Paterson stop and tail, and kept the trux in the bottom 5. But I disconnected everything but the reverse lights. Now several of them are out, one is black from mold. They weren't cheap either, think they were $45 each and I bought 10.
I bought 5 new led reverse lights but haven't put them in yet.
