Anyone who has or had this style of trailer light, give me your comments on use and performance. And what make trailer was it installed on.

Are you referring to the type of housing where the bulb is enclosed in a clear replacable sealed bubble?
If that's the one, my brother in-law had them on his trailer. Problem is, when the bulb burned out.... the replacement bulb/bubble was no longer available and he had to swap out the whole housing anyway.
Our group (three boaters with five boats) now only replace with LED's when the old lights go.

I had some made by Wesbar on a 1991 Magnum Trailer. They worked fine, never a problem for the 8 yrs I owned the boat and launched in saltwater.

My trailer originally came with a mix of the "bathyspheric," i.e. open at bottom/bubble of air at top s'posed to keep things dry, type light and the sonically sealed type light. The "bathyspheric" didn't last nearly as long as the sealed ones, meaning that the bulbs went dark sooner due to corrosion and then couldn't be replaced because they were corroded in place. The "bathyspheric" theory is good but in practice enough water (salt water in my case) spray/humidity gets to the bulbs to quickly render them useless. Recommend you either go with the sealed units or for a little more $$ the LEDs. My sealed units have lasted for over 7 years, other than the tail light someone struck in the parking lot and broke open. The LED replacement has so far also been troublefree.
