Very bright, great color, and I like the range of flash patterns. The instructions are very useful and descriptive, nothing is left to confusion. I have used these on a number of vehicles/trailers and like them very much. Installation is easy and they give you plenty of wire to work with.

Looking at the picture I was lead to believe that it was three colors. Red, blue and white. I should have read the fine print. It's only two colors. Red and blue. I found other uses for them so not a big deal. ALL WAYS READ THE FINE PRINT.

Very bright lights in a compact size. I use these as backup lights on my Jeeps.I also use them to light up the areas to the left and right of the Jeep when things get really dark and dicey.Have worked really well for 3 years.

When these arrive, They'll have a blue protective wrap on the lenses. They will be the correct color . You'll need to open the package and remove the coating. Great product.

We don’t use light bars at my utility. So I put 2 of these on the side of my work truck because my strobes being led only project straight ahead and behind. I had no side protection lights. I liked them so much I ordered 6. Had 4 installed on another of my employees truck one on each side at the front on each side at the back, and completed my truck in the same fashion. Life saver for sure.

As with all of the speedtech lights I have they are absolutely amazing. The brightness is absolutely amazing. Being in the towing and recovery business being seen in all conditions is of utmost priority. Which is why i run speedtech on all of my trucks. Great product at a great price
