Do these use the factory mounting holes?

Yes. They mount at the factory side marker positions—no drilling or custom brackets required. You'll bolt them in where the originals sit.

Will I need new bulbs or wiring?

That depends on your current setup. If your factory wiring and bulbs are good, these markers will work with them. If you're replacing burned-out markers, you may need fresh bulbs—grab those separately if needed.

Can I install these myself?

Absolutely. You'll need basic hand tools and a few minutes per side. Grab your socket set, pull the old markers, bolt in the new chrome units, and you're done.
