    Ditch the gasket and use 5200

    Installed on my 94' Four Winns, used a bunch of 5200 to assist with sealing everything up over the included gasket. Wires are kind underwhelming but they worked.Wired it in on a cheap prefab LED light bar wire harness.Have had the boat out several times since install, yet to find water has gotten into the lense or lights.They are pretty bright, if you are in the shallows even more so but one thing I didn't anticipate is how many bugs they attract :/

    Good addition

    Bright and fully functional. There was a bit of work to find the right spot to mount them and making some adjustments. However they look good and out of the water they are very bright.I’m redoing my boat and this is a wonderful addition for this project.

    Better than expected

    Brighter than expected I’ve only had it in the water once but I’ve had no water intrusion. I did use 4200 instead of the gaskets but the gaskets do look like they would do the job just fine pretty impressed so far.
