Hello all! I've got a 2006 Pontiac G6 base sedan with the 3.5 V6. Have had it for a little over 2 years. I've been wanting to replace the headlight assemblies for some time now and finally got around to getting some new ones. I ordered a set from 1AAuto and ran into fitment issues. There are large gaps below the lights and the bumper which aren't there are on the stock GM assemblies. When you orient them to where they should sit against the bumper there are gaps on the outside edge where they don't sit flush there anymore. The mounting brackets toward the outside edge also have large gaps between them and where they mount when sitting against the bumper. I don't know how they can be this off. I took pictures as well. I contacted 1AAuto explaining the issue and wanted to send them back for a full refund. They apologized and issued a full refund but said they did not want them back. They did want the pictures though for their QA team. The brand on those lights are "Vision".

I thought I'd try some Depo's instead and ordered them off Amazon. Same fitment issues when installing them. Getting pretty irritating. What gives? The GM part # on the old lights is 15783700. Apparently there have been a whole bunch of different GM part numbers for these that have existed and been superseded. Have the dimensions/design changed slightly? I don't know what my options are, or if I even have any in order to get new assemblies that fit like the old ones. I may be stuck refinishing the old ones to clear them up but I really don't want to do that if I don't have to.

Anyone here seen this issue before or have any ideas? Thanks in advance for any help!

I'm guessing no one has seen this before or has any ideas? I'm probably just going to have to send the Depo's back to Amazon for a refund and refinish the old headlights.

I see the gap and chalked it up to the front bumper cover on my 07. But maybe it is the light assemly. I will have to check. When i pull it out of storage in spring

Finally got around to refinishing the lights. Used the 3M heavy duty kit with clear coat and wet sanded through all the grits. Night and day difference. They aren't perfect (old lenses have a bit of crazing toward the sides) but it's way better than having huge gaps with new aftermarket assemblies.

I bought Spyder brand and they fit my G6 perfectly. I started out by getting the original lenses polished but within 6 months they were fogged over again. Car looks so much better now.
