Replacement LED brake lights

[Msu50000]

One of the brake light housings on the trailer is no longer there, found that out when we got to the campground this weekend. Perfect time to replace with LED, I've done a quick search on eTrailer/Amazon with mixed results. I need something about 8.5" x 3.75". Most of what I'm finding are a bit smaller. Does anyone have any recommendations and also what type of sealant do I use once mounted?

Found these, now that I've had a few minutes to look. They appear to be the same shape and style as what I have on there now with the LED instead of the old style bulb.

Thanks Bud, the diagrams showed those lights slightly under 8" wide, I'll have to get the light off once I'm home and see what I have to work with, I've only measured the base plate for the light housing.
