Pros: Surprisingly bright, wide range of flashing patterns for all colors in the description. Wires & electrical insulation is thick. It remembers which flashing pattern and color you last used, so you only have to flip the power switch if you always use the same settings. Cons: The led bars are water resistant, they are not water proof. These work best if you mount them inside your vehicle or inside a water proof enclosure. Basic wiring info: The power switch & button are not backlit for nighttime use, so plan accordingly. The wires are long, but the odds are that you will need to add an extension between the power switch and first light bar. There are 3 wires that run to the first and then to the second light bar: a hot, a ground, and a control. The hot carries about 1 amp / +12vdc and the control carries about +4vdc. When you press the control button, it shorts the control wire to the ground wire, which causes the control modules in the light bars to change the flashing pattern. Hold down the control button for 3 to 5 seconds to change the color. Some people forget this important detail or never see it in the instructions.

Muy buena calidad y excelente producto

The light itself is great, bright, easy to change patterns and colors. The only issue, I had was mounting. The light housing it large, the brackets included are not much bigger. If, you are mounting on a flat surface you will be fine. Mounting to a vehicle with any curve or slight degree difference, you may have trouble keeping them 100% aimed. If, you are mounting these to a vehicle and not a four wheeler or go kart or small vehicle, buy three strand wire and make your own extensions. The momentary switch that controls pattern and color is wired to the on and off power switch. The switch itself has like a three foot power pair of wires and the wires to the lights are max like 10 feet. You cant run the lights from your bumper to the cab or tail of your car to the center console without extra wire. Otherwise, great lights so far.

Muy buena calidad y muy buena iluminación.
