What color is legal for my vehicle?
Many led bulbs in the market are polar sensitive, it requires the led bulbs positive must connect with 12V power positive or it will not light up. So for the polarity bulbs, if the bulb doesn't light up, please flip the bulb 180° degrees and try to install again. Yet for the non-polarity bulbs, you will not worry about this polarity issue. no matter how you connect the bulb into the original socket, it will light up. Most of our miniature bulbs are non-polarity bulbs for we have made a great improvement to make it more easier to install for the customers. Back to Top

Usually for led bulb brightness, it is calculated by the light output lumens, the lumens is higher, the bulb bulb is brighter. Yet please note, when you care of the lumens, also please care of the heat dissipation, for many led bulbs are bright in the market, but easily burned out,because the heat dissipation is bad. Our miniature bulbs are built in IC driver to control the stable current, and built in better heat dissipation,which will makes the bulbs' life span much longer.Back to Top
