Really fast shipping , great affordable prices.

My mechanic removed the factory one and the replacement one has a different bulb size, I chatted with the expert at 1-A auto and he said that the different vendor had a different size bulb and would be okay, my mechanic just wanted to make sure because he said it was in a difficult place to replace it, otherwise it fit, connecter and thread size.
