Using this light bar on your 2009 - 2013 Subaru Forester is easy. First, gather all the necessary tools for the simple bolt - on installation. If you want to enhance visibility, you can mount up to 4 driving lights on it. Make sure the lights you choose are up to 6.5' in diameter and 1.5' in depth. When it comes to maintenance, regularly check the powder - coated finish. If there are any scratches, touch them up to prevent rust. Also, check the bolts periodically to ensure they are tight. And remember, the driving lights are sold separately, so you'll need to purchase them if you want to use additional lights with the bar.
