Wire Gauge for 20 LED Trailer Clearance Lights on 150-Foot Run

I need to run 20 clearance lights around a 50 foot modular trailer all led at 0.048 each using 12 gauge wire on one circuit not running any run longer than 150 feet is that good

Twenty (20) individual LED clearance lights that each draw .048-amps at 12-volts will have a total current requirement of less than 1-amp. But a long 150-foot total wiring run will mean some losses. I recommend using dual runs of 10-gauge wire # 10-1-1 to ensure you get the full brightness from all those LED lights.
