Fitment can vary by trim, package, market, and body style, so it is smart to compare the bulb listed here with the one already installed in your vehicle. The 2015 SRX may use different bulbs for halogen versus HID headlight systems, and some owners choose LED aftermarket replacements for brighter output or longer life.
