Smoked look

TL-18 4” red lights are nice if you’re trying to match the smoked look. Not very bright from a 45 degree angle. Still a nice looking light if you’re looking for the smoked look.

perfect replacement to the poison spyder truck lite round lights for my jeep crusher guards

after 10 years my truck lite round brake/tail light leds began to dim and die away. these are great replacements that are brighter and 1/3 the cost of truck lite.

Carlee Gibson
Updated old RV tailights

These were easy to install as a direct replacement for the old and cloudy lens tail/brake lights on my RV. Exact same fit, installed with ease and even was able to use the old wiring harness connector. Great value too.
