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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10129959-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10129959-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10129959","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"lighting","name":"Lighting","parent":null},{"id":"headlight","name":"Headlights","parent":"lighting"}],"codes":[],"topics":[],"vehicles":[{"make":"NEWMAR","model":"DUTCH STAR","year_from":2017,"year_to":2018,"match":null,"vehicle_ids":[]},{"make":"NEWMAR","model":"VENTANA","year_from":2017,"year_to":2018,"match":null,"vehicle_ids":[]},{"make":"NEWMAR","model":"VENTANA LE","year_from":2017,"year_to":2018,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
