Will these bolt straight onto my car or do I need to modify the mounting points?

These are designed for factory mounting locations on your Grand Am. Test-fit before final installation to confirm alignment with your specific vehicle's mounting tabs and wiring harness.

Do the LED daytime running lights work independently from the main beam?

Yes. The integrated DRLs function as daytime running lights while the main projector bulbs handle low and high beam duties. Wiring integrates with your factory harness.

Can I return these if they don't fit when they arrive?

Confirm fitment specifics with ModSupply before ordering. Once installed or modified, fitment issues typically fall outside standard return windows — verify compatibility with your exact vehicle configuration first.
