I have a fishing/patio dock on the corner of my yard that is on the main canal for boat traffic. I have been looking for dock, deck lights that would be red and green, Left, red for port side, Right green for starboard side. I have 3 brands of deck lights currently, all are blue and white, one has red, for the end of the dock. Finally a deck light that gave me the colors I needed. At Christmas, I'll switch every other one to Green and Red, Christmas decoration are done. :) The VOLISUN lights are the BEST I have seen on the market and I have used a lot of different brands. When advertised they can be driven over, they are not kidding, these lights are that tough. The box is very flimsy for the weight, twice the bottom of the box came open going down to the dock. all 12 fell hard on the concrete, not a scratch and still worked perfect. TIP, tape or hold the bottom of the box when carrying. The night photos do not do the VOLISUN lights justice, they are much brighter in person. We have a lot of boat traffic at night. Having a lit up dock is beneficial to night time boat traffic, many of them are coming from the beach bars and need all the navigation help they can get. The canal is very dark at night. The VOLISUN lights cost a few dollars more, but so worth it in the quality AND being able to choose a color of you choice. These light are Excellent. When I took the photos last night, one of my neighbors started clapping. :)
