2008 SE V6. Wanted to replace headlamp assemblies due to fogging and some bulbs not working. Ordered replacements from CarParts.com and apparently I ordered halogen replacements instead of replacements that would accommodate Xenon/HID. I cannot return the 2 headlamp assemblies and when looking at correct replacement parts, costs range from $300-$500 per assembly. I have 3 questions - can anyone suggest a reputable site to try to purchase the correct assembly (part label shown below for RH assembly; LH is 26060)? Can I replace just the bulbs and leave the original assemblies installed? Can I somehow "convert" to use the halogen only assemblies? The original wiring harness has a grey connector for the HID ballast whereas the new headlamp assembly uses two halogen bulbs and has no ballast connection.
