You might still check inside the lights from time to time.
I bought the entire fixture which came with 2 LED brake/tail lights and one incandescent backup installed in the base.
A day later after a night of heavy Louisiana dew, I noticed water collected in the lens of the backup light lens. I removed the lens and caught what the problem is.
The black base has an outer lip and an inner lip and the lens cover fits between the two (I guess I should have taken a picture for illustration). Water gathers just under the outer lip, rolls to the lens edge then falls in the lens channel overcoming the inner lip.
Basically this entire recess that the lens fits into needs a gasket. I was not able to find a large enough o-ring but I recall that silicone doesn't "like" the vinyl material of the black base. I removed all the lights and lenses, filled the recess with a black silicone, allowed it to cure and re-installed the lights and lenses. The lens edge didn't go in as far because of the silicone but I did see it compress the silicone. Once all the lights and lenses were installed I used a towel to rub off the silicone waste.
It worked perfect. No other occurrences with water even with some of out heavy thunderstorms lately.
I mention this even though you now have all LED including the backup, but the water still gets inside behind the LED fixture. Not inside is but in the recess for the fixture. Left unchecked it could migrate into the LED fixture.
