Buick LaCrosse: Turn Signals when Towing a Trailer
The turn signal indicators on the instrument panel flash whenever signaling a turn or lane change.
Properly hooked up, the trailer lamps also flash, telling other drivers the vehicle is turning, changing lanes, or stopping.
When towing a trailer, the arrows on the instrument panel flash for turns even if the bulbs on the trailer are burned out. Check occasionally to be sure the trailer bulbs are still working.
