The media could not be loaded. These lights are amazing and bright for the money. Easy install and can mount anywhere if you have the patience to strategically place them. I recommend 14 GA wire of each color associated with the harness for premium use. I look like a rolling Christmas tree and there should be no reason drivers can't see me working a fire call.

trying out for snow storm visibility, works as advertised

So unless you are proficient with the wiring of automobiles you might have a tough time connecting this. If you hook up the wrong pair of leads you risk blowing the light rendering it useless. So be careful if you go shotgunning the procedure and randomly touch wired to see which does what. I'll probably just return it since there is no instructions on how to connect it. Shame, looks like a sweet device...

Edit 5/20/19: The wiring is quite simple actually, red is 12V DC positive, black is ground/neg, yellow is 12V DC to a momentary switch of your choosing (meaning it goes back to open after you release the button) which changes the flash pattern. I was also contacted by Andrew via a phone call, he reached out to me to find out what exactly was the issue and after some discussion I came to the conclusion that this is a seller who truly cares about it's customers. While this light here won't work in the application I had it set aside this time I was thoroughly pleased with the device itself and will likely in my next project set-up probably design around it so that I CAN use the light I was THAT impressed by it (I build high end custom electric skateboards and use the lights as way to get drivers attention - sick of being hit & run by careless drivers - what better way than with flashing red & blues?). Five stars for since the seller reached out and took the time to listen to their customer.

Hey Amazon: Lets get the ability to bold and italicize words so that is looks as though we are trying to stress a certain word(s) and not give the impression WE ARE YELLING WHEN WE TYPE. Just a suggestion...

I ordered red/white combo x2 lights. One came red/white. One came red/yellow. Because i needed the job done quickly I went ahead and used them. Much prefer the red/white.

I have not installed these yet, as I am still waiting on other components to my system. I have received, opened and downloaded instructions. The product is very good quality, the instructions are simple, clear and concise. I hope to be installing them soon to see how well they work. I have no doubts. Thanks.
