Nilight 4Inch Round Trailer Tail Light 12LED
Product description
This round trailer tail light brings brighter signaling and tougher sealing for on-road and off-road use. It pairs turn and brake functions with a low tail light mode, giving clearer visibility when you need it most. If you tow frequently or maintain trailers, this light helps improve rear signaling with a compact footprint.
Key takeaways
The design centers on durability and reliable attachment. The light uses upgraded 3030 SMD LEDs for stronger output and a wider beam, according to the manufacturer. The improved grommet notches and three bulges hold the lamp firmly in place on the bracket so it resists shaking and loosening during travel. Note that the fit requires a 0.39" round hole, so check your mounting cutout before ordering.

Why it makes sense
The unit is silicone sealed and rated IP67 for water resistance, which helps the light withstand rain splash and wet road conditions. The mounting bracket is metal with black powder coating to reduce paint loss and rust. Installation is straightforward, with a rubber grommet, bracket and nut fastening process, then a three-wire electrical connection to a DC 12V system. Expect a brighter turn and brake signal plus a dimmer tail lamp level for nighttime visibility.
Who it’s for
It makes sense if you need a compact replacement light for trailers, trucks, RVs or boats that runs on a 12V system and fits a 0.39" hole, offering stronger LED output and a secure mount. Not the best choice if you cannot confirm the hole diameter or if your vehicle uses a different connector type, because proper fitting depends on those details.
Care & maintenance
Clean the lens occasionally with mild soap and water and inspect the grommet and bracket fastenings after heavy use. Ten in account that prolonged submersion is not covered by normal use despite the IP67 rating, so avoid persistent underwater exposure.
