Here’s a handy little electronic part – a headlight level sensor that works on a bunch of Toyota and Lexus models, plus even the Mazda RX-8.
Main part number is 89405-48020, but it also crosses with 89406-48020, 89406-53010, and tons of others like 89407-48010, 89407-48020, 89408-30110, and more.
Aftermarket Products is the brand, so it’s a quality aftermarket piece.
This sensor tells your headlights how high to point based on the vehicle’s load and angle, so you don’t blind oncoming traffic or miss the road ahead.
