Bulbs
A dead bulb is the cheapest fix on the truck and the easiest to get wrong — bulb bases and sizes are model-specific, so the H11 in one rig is a 9005 in the next. This is a small, growing set of factory-replacement and upgrade bulbs for headlights, fog lights, and markers. Match the OE size for your truck, confirm socket type, and replace bulbs in pairs so color and output stay even.
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.
