# Service bulletin RSB 509

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10129959
- Published by NHTSA: 2018\-03\-12
- Manufacturer's number: RSB 509
- Manufacturer's date: 2018\-02\-08
- NHTSA component: EXTERIOR LIGHTING:HEADLIGHTS; ELECTRICAL SYSTEM; EXTERIOR LIGHTING:HEADLIGHTS:HIGH/LOW BEAM DIMMER SWITCH

## NHTSA's summary

Newmar Corporation has decided that certain 2017\-2018 Ventana, Ventana LE, and Dutch Star motorhomes built on Freightliner Chassis fail to comply with Federal Motor Vehicle Safety Standard \(FMVSS\) number 108, ?Lamps, Reflective Devices, and Associated Equipment.? On certain motorhomes, if the headlight high beams are activated, only the high beam bulbs illuminate. The intention of the high beam function on the affected coaches is to have both the high beam and low beam bulbs illuminate together. Issue: Driving a motorhome at night without the required illumination of the road may reduce the driver?s visibility, increasing the risk of a crash causing injury and/or property damage.
