It is too early to speak, I have had them for about a month for vehicle emergency lights so far they seem good, sturdy. Time will tell! They are both spotlights and beacon lights, and if you want only a beacon light or only spotlights, the color is red and blue. I give it 4 stars and not 5 because I have been using them constantly for a month. I will come back after months and add another star, guys, it's worth it, I highly recommend it, it is suitable for all weather conditions!
