So far these turn signals are very good. Bright and visible even in moderate daylight. Well built, aluminum construction. Easy to set up. I didn't use the wiring harness, opting instead for the cigarette lighter option. Minus, the manufacturer installed plugs at the end of the cable. The plugs are huge so you have to drill a big hole (1/2 inch plus) to thread them through. A little advice. I installed a sample with a large hole but stopped when I realized I had to continue with the size. Instead, I used a Tweek screwdriver (very small) to insert the metal tabs that hold the pins in the forks. The forks are transparent so you can see what you're doing. After removing the wire from the connectors I was able to insert the cable with the connectors into the smaller hole and it was easier to tighten them behind the case. On the other hand, I folded back the tabs on the connector and snapped the connector back into place. Just think about which cable goes where. The only downside is that the "brain box" mounting plate is in a weird place and is practically unusable. I chose to place mine under the driver's seat so I can run cables under the floor to my truck's center console. It worked pretty well and it's not visible from outside of my path. I'll update my post if they don't last or if I run into other problems.
