Headlights rattle/move around
The good news is that the lenses are clear and, contrary to the description, bulbs are included. The bad news is that the metal ball/plastic sockets used to hold the units in place are not nearly as snug as the precision OEM ones being replaced, so the lenses move around even when bolted tight. I wound up shimming them in place with some cut pieces of plastic tubing. Sad that aftermarket stuff often looks good, but just doesnt work as well as original equipment.

Headlights have too much play.
The headlights are exact in every way as the OEM, except for the fact that the brackets have too much play. After tightening down everything and ensuring proper fit, the headlights wobble. I had a new set sent to me and had the same issue with those as well. I think 1aauto should research the "Vision" brand because there clearly is a quality issue. I decided to get them at the dealer with no issues after install versus going through the hassle of possibly getting the Vision brand from another online retailer. On a positive note, 1aauto has excellent customer service, and are extremely helpful they make the return process very easy. I recently bought headlights for my mothers 97 Chevy Lumina and encountered no issues, she was very pleased.

good price but loose fitting
Good price and fast shipping. Headlights are loose when installed. Not like the originals. Was able to add some spacers to get a tighter fit. OEM lights are $175 a piece so these are a bargain.

Toyota tacoma headlight replacement
Grest replacement at a reasonable price. I had to do minor adjustment to get the correct light view I wanted. Overall I would recommend this product to other people. I only gave four stars because I thought the glass would be thicker

Theyre just ok. They fit properly, however they are significantly too loose. This would be an easy and inexpensive fix on behalf of the manufacturer and is a common complaint in the reviews. Ill be looking for a way to shim them in order to take out some of the wobble.

toyota head lamp and side light assemblies
Bought headlamps for right and left. One of them was missing an internal subassy that wasnt connected. Two screws missing but found them in the box. No way to reassemble other than to drill holes through the plastic housing. The other came fully intact. The fit wasnt that good on either until I snipped off the end of one of the clips. Ordered two side lamps one came with a bulb the other without. Had to modify the clips to make them fit snug.

Do these need to be aimed? Is there adjustments on the mounts for that?
Kevin K May 14, 2016
Yes, there are adjustment screws.
Vince H May 14, 2016
They do need aimed once there installed! I installed myself and then had my mechanic aim them!
Nicholas F May 14, 2016
Great overall lights for the money!
Nicholas F May 14, 2016
Yes, these definitely need to be aimed. I adjusted the screws to match the approximate number of threads exposed on the old pair removed...way off and beams were in the trees.
Chris T May 14, 2016
Yes they will need to be adjusted and yes the adjustments are built into the housing.
Nicholas D May 14, 2016
adjustments may be necessary and they have adjusters built in
Brian F May 16, 2016
They were pretty close when I installed them and were very easy to adjust for fine the way,the install was a piece of cake!
