STDYSUN LED Emergency Strobe Lights Bar 2Pcs Red Blue Change White Double Color Warning Police Grille Lights Bar Surface Mount Fit for Motorcycle POV Utility Construction Vehicle and Tow Truck Van

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.

Bought to add more lighting to the rear of my vehicle used on the highway.

Very easy installation and function well, I think the price is okay and I recommend putting a fuse when installing as it doesn’t come with one for safety

Lights work well . The wiring supplied was a few feet too short . I had to cut connectors and add my own wiring. Also it would have been nice to have an illuminated power switch.

Could be brighter.

The media could not be loaded. Awesome product for the price the switch could be a little better comes apart easily but all around good product

After spending 3 hours running wires, mounting light, securing wires, connecting to battery, mounting switch. I tried switch and nothing. Then flipped again and again, finally worked. Then turned off and flipped again and it seemed to work. I went behind vehicle the other morning when it was dark and noticed the left light was strobing very dimly. The switch was OFF! This is a huge problem. So now I have to spend 3 hours pulling the POS out and shipping back. Do not buy

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.
