Grote 49172 Red Bar Lamp

The Grote 49172 is a rectangular red marker light designed for RV exterior use. It carries fifteen incandescent lamps in a single polycarbonate housing that meets FMVSS 108 and SAE P2 standards. The unit mounts permanently via a bracket and connects through blunt-cut wires compatible with Grote 69710. It suits owners who need a long, DOT-compliant marker strip.

Sustained load behaviour

Each lamp draws roughly one ampere, so the full bar pulls about fifteen amps continuously when lit. Incandescent output remains steady as long as vehicle voltage is stable, with no thermal throttling or duty-cycle limits. The polycarbonate lens and housing tolerate the heat generated during extended night driving. There is no PWM dimming or flicker to manage over long periods.

Thermals noise and power

Incandescent lamps convert most input power to heat, so the bar becomes warm to the touch after prolonged use. The polycarbonate housing dissipates that heat passively without fans, making operation completely silent. Current draw is a fixed fifteen amps at nominal twelve volts, imposing a predictable load on the RV electrical system. No additional cooling or noise mitigation is required.
