If I could give 6 stars I would
Lights exceeded all my expectations. fitment is excellent, adjusters work as they should, clearer than OEM. I have purchased lights from another company and they failed in every way. The didnt fit properly, Left/Right adjustments also moved lights up and down so they could never be adjusted properly. They barely provided enough light to see down the road. Should have bought lights From 1A Auto the first time. Plus 1A Auto was less expensive
