Step 2: Left/Right Turn Signal Installation
Step 3: LED Indicator Installation
Install the Left LED indicator and Right LED indicator in a location that is visible to the driver, ideally in
or around the vehicle's A-pillars (see Fig 13, Fig 14). Place the LED indicators away from the side curtain
air bags, so as not to hinder the deployment of airbag function. Appropriate placement is usually at the
lowest part of the A-pillars, but you must consult the vehicle manual.
