In the last year or so I have bought about four of these types of turn signals from three different suppliers. The design of the light modules is identical, unfortunately identical. This is an extruded aluminum tube with end caps. The LED modules are soldered to a roughly 1/32 inch thick piece of aluminum, the optics are built into the window, and the window and aluminum LED pad are bolted to a single piece of metal that is assembled into an extruded aluminum tube. The drivers are proprietary, but most of them follow the CANBUS topology, which allows the signal to be transmitted over a three-wire harness. Despite this, there are no gaskets on the entire module, and by design it's almost impossible to seal them once the LEDs are sealed, they thermally float and there is no way to dissipate the heat generated by the LEDs. Combined with overloading from using the wrong resistors, the LEDs will scream very brightly and burn for a very short time. White LEDs have a forward voltage of 3 to 3.5V. Yellow LEDs are at least a volt lower. As a result, some failed LEDs have turned yellow. It can happen that the 3-wire plug that leads to the decoder circuit board no longer works and that the light head that has not been weathered will corrode. Due to either moisture ingress or corrosive flux residue, the controller inexplicably stops communicating with the lamphead and half your modes will not work. By definition, CANBUS is a high-speed network that requires quality cabling to function properly. Thus, it is sensitive to wrong wiring. Most CANBUS communication problems are caused by bad wiring. The light bar is used outdoors, especially when mounted to the front. Moisture enters while driving. If you're in Florida like me, that air is salty. I haven't found any reliable waterproofing solutions despite trying many different mediums. The basic design should allow for quick and easy production, but with almost no emphasis on durability. I was able to rebuild the lightbars with individual SAE compliant IP67 modules, each costing about half of this lightbar, and reuse the controller that came with this or similar lightbars, but it's not easy enough to do a DIY tutorial . They will work at the end of the line, but not for very long. Even if you don't put them outdoors, they are toys and not serious equipment. They are unsafe, unreliable and do not meet SAE requirements for directional strobes (SAE W-2 08 DOT).
