The Blazer B165 LED round snap-in license light is designed to conform to applicable U.S. FMVSS108 and Canadian CMVSS safety standards and meet DOT requirements for license lighting. This 12V accessory is also ideal for courtesy or instruments lights. Two lights are legally required when used for license plate illumination. LED technology draws significantly lower power than traditional incandescent lighting and the long-life LED lamps do not require bulb changes giving you years of maintenance-free service. The chrome-plated light snaps into a 1-1/4" diameter hole for easy installation.
