S/T/T Light 4in Red - 571.LG40R

Part number 571.LG40R

Automann’s selected fields for 571.LG40R specify a sealed 4in round red incandescent stop/turn/tail configuration with grommet mounting, PL-3 and 12V, a polycarbonate lens and 0.48A draw. Its LED-use direction does not make it an LED lamp, and the separate 50-piece wrapper or kit association does not establish this owner’s supplied quantity.

Confirm the exact application and configuration before selecting this part. Reference numbers and similar configurations do not guarantee interchange.
