I bought Double White. Good price. The LEDs are very bright. It hurts to look straight into a line from 3 feet away. The cigarette lighter power adapter is neatly assembled and secured. (Just unscrew the nose of the fuse). The cable size corresponds to the power consumption. Current draw was measured at 12.8 volts DC and was a maximum of 1.04 amps with BOTH light units. There were significantly fewer flash modes, but since the handheld meter I used didn't have peak detection, I can only say "less than" 1.04 amps. Cigarette Lighter/Power Adapter. The wiring has plastic tab-locking plugs that let you buy extension cords for a supplier's "plug-in solution," but seriously, just cut and lengthen them yourself to save some money. The rocker switch on the control panel simply cuts power to the device to turn it on and off via the power cord (red). The button is connected to a white wire and when pressed simply connects the white wire to ground to allow the turn signal to change modes. The black wire is obviously grounded. The device has a final flashing sequence after switching off. The Bad: (Considering the price, it was difficult to see anything really "bad" about them.) The control panel panel is NOT weatherproof. Cable connectors between LED modules are not weatherproof. Their price means you don't get weatherproof connectors. LED modules are only protected against water. (They are NOT waterproof, so do not put them in water to try to make your goldfish have an epileptic seizure). Overall - 10/10 would buy again.
