Headlight Bulbs: LED, HID, or Halogen Upgrades
Picture this: your headlights look dim next to every new truck at the gas station, and you want brighter light tonight, not after a week of forum research. LED, HID, and halogen bulbs will all beat stock, but they are not interchangeable jobs. If you run a reflector housing, LED is usually your lane. If you run projectors, HID often does it better. So pick your housing type first, then pick the bulb type built for it.
We have bench tested over 300 LED headlight bulbs for beam pattern, brightness, and color, and we keep the results in what we call the Headlight Revolution Big Book of Bulbs, the same reference our customer service team pulls up on every call. Here is the catch: the single biggest factor in a clean beam pattern is how closely the LED chip mimics the shape and position of your original halogen filament, not the brand printed on the box. Round COB-style chips and other designs that spread light inside the housing lose out to filament-matched arrays. We also flag any bulb that places its driver right next to the heat source as a reliability risk before it ever gets listed for sale.
Find your bulb type
Plug and play LED bulb kits built for factory reflector housings, our current pick for the brightest instant-on light in that setup.
Complete bulb and ballast kits for drivers converting a halogen projector housing to true HID output.
Replacement bulbs and ballasts for an HID system already installed, with color options that can mimic stock halogen or match a modern LED look.
Upgraded halogen bulbs for drivers who want more light than stock at the lowest cost, and who accept the shortest lifespan of the three options.
Turn signal & marker bulbs for owners rounding out the rest of the light housing to match a new headlight bulb upgrade.
Anti-flicker modules and load resistors for anyone hitting hyperflash or warning lights after switching bulbs to LED.
Relay harnesses, sockets, and connectors for anyone wiring in a bulb upgrade the right way instead of splicing into factory wiring.

Start with your headlight housing type, reflector or projector, then click into the bulb category built for it. From there, if you are also chasing turn signal or DRL issues, Signal Bulbs and PWM & Resistors will save you a return trip. Worth noting, if you are still deciding between bulb technology and a full assembly swap or a retrofit, those categories are built for that bigger project.
