Bulbs
Replacement and LED upgrade bulbs for headlights, fog lights, turn signals, brake lights, reverse lights and license plate lights. Most are from ORACLE Lighting, with KC HiLiTES halogen bulbs, and cover Jeep Wrangler and Gladiator, Toyota Tacoma and 4Runner, and Ford Bronco. Confirm the bulb type, such as 3157, 7443 or H4, and whether the listing is a single or a pair.
Bulbs FAQs
What size replacement bulb does my truck use?
It depends on the exact position and model year — headlight, fog, and marker positions each use a specific base like H11, 9005, or 194. Check your owner's manual or the size stamped on the old bulb, then filter by year, make, and model. Never assume the front and rear take the same bulb; most trucks mix several sizes across a single vehicle.
Are LED replacement bulbs a drop-in upgrade?
Sometimes, but not always. LED replacements match the factory base and boost output, yet many trucks need a decoder or resistor to stop flicker and dash warnings, and beam pattern in a reflector housing can suffer if the LED isn't built for it. For fog and marker positions LEDs are usually painless; for projector headlights, results vary by housing.
Should I replace headlight bulbs in pairs?
Yes — replace headlight and fog bulbs as a pair. Bulbs dim gradually, so a single new bulb next to an aged one gives uneven color and brightness. Halogen bulbs also fail on a similar timeline, so when one goes the other is usually close behind. Pairing keeps output balanced and saves a second trip under the hood.
