Do I need bulbs for these headlights?

These units come as complete assemblies with the LED DRL integrated. You'll need to confirm bulb type and availability for the low and high beam positions before installation — your owner's manual or a parts diagram will specify the exact bulb fitment.

Will I need to do any wiring or can I just plug them in?

The housings are designed for factory mounting points, but electrical connections depend on how your vehicle's original harness routes. Some buyers splice into existing harnesses, others use plug-and-play adapters — test fit the assembly before committing to your wiring method.

What if one headlight fails after I install it?

Contact ModSupply directly with your order number and photos of the failure. Defects are handled on a case-by-case basis — most issues are resolved quickly, but return shipping is the buyer's responsibility unless the unit arrived damaged.
