Description
PDC PT8620 is a 4-inch round double-face fender pedestal lamp with a red lens on one face and an amber lens on the other, mounted in a chrome zinc die-cast housing. Direct replacement for the Grote 53000 — same 4″ round footprint, single-post pedestal, 1157 dual-filament bulb, and 12V wiring. Common on heavy-duty truck fender pedestals where a single lamp serves as both the rear stop/turn (red) and the front side turn (amber).
