Frequently Asked Questions
Will these bolt directly into my existing headlight buckets?
Yes. These mount at factory attachment points — no drilling or custom brackets required. Test-fit before final installation to confirm clearance with any aftermarket components.
Do I need bulbs, or are they included?
Bulbs are not included with these assemblies. You'll need to source the correct LED bulb specification separately and confirm compatibility with your electrical system.
What's the return process if these don't fit my truck?
Contact ModSupply customer service directly for return eligibility and shipping instructions. Keep original packaging for inspection.
