Tbrn Signals When Towing a Trailer The arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also flash, telling other drivers you're aboutto turn, change lanes or stop. When towing a trailer,the arrows on your instrument panel will flashfor turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It's important to check occasionally to be sure the trailer bulbsare still working. Your vehicle has bulb warning lights. When you plug a trailer lighting system into your vehicle's lighting system, its bulb warning lights may not let you know if one of your lamps goes out. So, when you have a trailer lighting system plugged in, be sure to check your vehicle and trailerlamps from time to time to besure they're all working. Once you disconnect the trailer lamps, the bulb warning lights again can tell you if one of your vehiclelamps is out.
