Last fall, Truck-Lite introduced for the reefer market two LED trailer dome lights whose diodes have a rated life of over 100,000 hr. The first product, the 80250C, is designed with the same dimensions as current fluorescent lamps, making it easy for retrofitting or use as a new product straight from the OE. The white LED uses multi-volt technology, Truck-Lite explains, rated to run between 10 and 30 volts.

LED technology, Truck-Lite points out, is an excellent fit for refrigerated trailers since LEDs work extremely well in cold temperatures. The manufacturer also states it has given the LED dome light a low profile design so drivers loading/unloading the trailer won't have a problem with insufficient overhead clearance.

The company says another advantage of the LED design is its “instant-on” technology. As soon as the operator turns the switch on, the LED is on and as bright as it will get, according to Truck-Lite, meaning the driver doesn't have to wait for the dome LED RV lights to warm up before unloading cargo.
