Using this Rally Innovations light bar is easy. First, gather the driving lights you've purchased separately. Then, simply bolt the lights onto the light bar. Make sure they are securely attached. When installing the light bar on your 2011 - 2014 Subaru WRX or STI, follow the simple bolt - on instructions. Check that it aligns well with the OEM bumper. As for maintenance, keep an eye on the powder - coated finish. If you notice any scratches, touch them up to prevent rust. Also, regularly check the bolts to ensure they are tight. Don't use harsh chemicals when cleaning the light bar, as this could damage the finish. Just use a mild soap and water solution for a gentle clean.
