With proactive alerts you can improve your towing confidence stay focused on the road ahead and gain some peace of mind that your surroundings are always monitored. Towtal View LaneGuard by Air Lift offers Blind Spot Detection (BSD) and Lane Change Assist (LCA). These features cover blind spots and make changing lanes safer while LED light strips keep you aware of everything. 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. Laneguard is best suited for smaller trailers except for trailers with rounded rears. The radar sensor mounts to the rear of the trailer and is required to be level and perpendicular to the ground. 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. Backed by Air Lift’s 2-year warranty.
