I believe I went with attwoods too, the original fixture lenses were beat and no longer clear turned opaque, so went with entire fixture.
The Nav lights are rated by miles, as I recall.
The red and green lights are way brighter than originals, the top white light was briter too, but not by as much as the red & green ones.
And the white is the usual different LED tone white vs. incandescent bulbs.
I do never expect to turn on the NAV lights again and not have all three go on and no more intermittant type activity. I hope.
Between the LED deck flood lights and LED Nav lites, can leave them on all night for several nights AND days (I bet) and not be concerned at all about running down a battery.
No problem at all with construction quality of the Attwood lights. I found them at West and websites.
The fold down white light is same style but I selected the taller one and custom cut the tube to the height I wanted, a little bit taller than original since the radar scanner was almost as tall.
