Some buyers say that the light test is not on, and this one is divided into positive and negative levels. If it is not on, plug it in in reverse :) The base has two contacts. If it is not on, you can move the iron wire position, it's OK to match your vehicle light base!

Every lamp in the store will be strictly tested before shipment, and buyers can buy it with confidence!
