PROLED40-18R

LAMP 4 LED

This is a 4-inch round LED stop/turn/tail light for heavy-duty trucks and trailers. It uses 18 diodes to provide bright, instantaneous illumination for brake, turn signal, and tail light functions. Replacing old incandescent lights with this LED unit reduces electrical load by up to 85% and provides longer life and better visibility. You would replace your old or failed 4-inch round light with this to upgrade to sealed, solid-state LED reliability.
