Remark:

Because of the lower consumption feature of LED, most of our products have the error-free function. But some sensitive German car needs to load extra resistance to cancel the error code on dashboard.

Most of our car led bulbs have "Non-polarity" function, which means you do not need to distinguish the positive and negative in the socket, just need to plug in. Otherwise, please reverse the bulb and insert into the socket again when you find it does not light regularly.
