OEM QUALITY AND DOT COMPLIANT: Philips Vision bulbs meet the Department of Transportation requirements. Choosing original equipment bulbs reduces the chance of early failure thanks to their higher quality standards. ALWAYS REPLACE IN PAIRS: At the end of their life, lamps project less light, therefore reducing visibility. When changing a headlight bulb, it's best to change in pairs to ensure a symmetric light beam from both bulbs on the road. FEEL SAFE, DRIVE SAFE: Significantly whiter light to improve comfort and safety INSTALL SAFELY: When installing a new bulb, never touch the glass. Either use gloves or paper towel when handling. CONFIRM FIT: When using the Amazon part finder, be sure to confirm the POSITION and NOTES provided. For some vehicles, bulbs may fit some positions (fog light, low beam, high beam, or high/low beam), but not all. The POSITION and NOTES ensure Exact Fit!
