Sorry - cannot recommend
First - no problem with 1A auto. They handled everything just fine. The problem is with this product - it is an inferior product. I installed the lights (took about 3 hours) and within a week - the drivers side headlight had condensation and soon water. 1A auto did send me another one. Finally replaced it (took about 2 hours - getting faster) and I went to check them after some snow and rain. Seems OK - but now the passenger side has condensation. My only conclusion - cheaply made in China. DONT BUY THIS PRODUCT. Try another manufacturer.
