Designed for easy flush-mount installation and weather resistance, the lights aim to improve visibility to following drivers while fitting common 4\" mounting cutouts.\u003c\/p\u003e\n\n\u003ch3\u003eHow bright are these lights and what do the two brightness levels do?\u003c\/h3\u003e\n\u003cp\u003eThe pair uses 24 high-efficiency SMD LEDs per lamp behind a transparent lens to maximize output while managing heat. A low-brightness mode provides continuous running illumination, while the high mode is instantly brighter for braking and turning so vehicles behind can notice changes.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e24 red SMD LEDs per light for strong, even output\u003c\/li\u003e\n  \u003cli\u003eLow mode for tail\/running visibility\u003c\/li\u003e\n  \u003cli\u003eHigh mode for brake and turn signaling\u003c\/li\u003e\n  \u003cli\u003eTransparent lens for improved light transmission\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat does the IP67 rating mean for use in bad weather?\u003c\/h3\u003e\n\u003cp\u003eIP67 sealing indicates the lights are protected from dust ingress and can withstand temporary immersion in water, which is ideal for exposed trailer and marine environments.
