Do these mount at factory points or do I need to drill?

These bolt straight into the factory fog light locations—no drilling, no modification to the bumper or frame needed.

Does the switch come ready to install or do I need to hardwire anything?

The harness is pre-assembled with a toggle switch. You'll connect it to your vehicle's electrical system, but no splicing or crimping required on the light side.

Are the bulbs included and how long do they typically last?

Yes, H11 amber bulbs ship installed. Lifespan depends on usage, but standard H11 halogen bulbs run 500–1000 hours under normal conditions.
