Replace existing incandescent bulbs with high intensity true blue LEDs. These bulbs replace T5 bulbs that are found behind virtually all vehicle dashboards. Give some flare to those dull instrument panels, side-markers, dome lights, and courtesy lights with vibrant LED colors. Theses bulbs will never lose their color. They are also much brighter than stock filament bulbs and require much less power to run them. Less power consumption and longer bulb life compared to factory bulbs equals a win-win situation. Installation couldn’t be easier, simply plug them in and go. Each package contains five LED bulbs and step by step instructions. Don’t Change… Evolve
