Transform your towing experience with the ultimate advanced monitoring system. Towtal View LaneGuard Pro by Air Lift offers Blind Spot Detection (BSD), Lane Change Assist (LCA), and Rear Cross-Traffic Alert (RCTA) with an extended detection range for continuous monitoring of the vehicle’s surroundings, simplifying lane changes and reverse maneuvers. With proactive alerts, you can improve your towing confidence, back up better, stay focused on the road ahead, and gain peace of mind that your surroundings are constantly monitored. You’ll always know if something’s in your way while backing up, even if it’s dark or hard to see. LaneGuard Pro utilizes dual radar sensors mounted to the sides of the trailer at the rear. You’ll always know if you have a clear path when backing up and added reassurance. The LED indicators are to be mounted on the front of the trailer in view of the vehicle’s rear or side-view mirrors. The indicators light up solid if someone is in the blind spot zone and flash if someone is in the lane change zone with the vehicle’s turn signal on. The indicators illuminate or flash while in reverse if someone is in the rear cross-traffic alert zone. Best suited for larger trailers, including trailers with rounded rears. Backed by Air Lift’s 2-year warranty. Feel more confident and safely tow your trailer without worrying that someone or something might be in your blind spot or if you’re stuck in serious traffic and need to change lanes.
