Two years ago I built a car hauler. As far as road manners go it's been one of the most well behaved trailers I've ever had. What hasn't worked so well were the tail lights. They were the typical off-the-shelf product just like these.
The problem was: they weren't reliable. The bayonet bulb holders didn't maintain good contact. I had to remove the lens to fuss with one/both bulbs at least once every trip it seemed. So I replaced both with LED versions. Hopefully they will prove more durable. Time will tell. They're brighter, regardless. So it's already a value add.
