1984 Chevrolet C10 Headlights: H6054 Sealed Beam Specs & Upgrades
The square body Chevy is having its moment, and the 1984 C10 sits right in the sweet spot of that generation. Whether yours is a patina-rich farm truck, a slammed minitruck, or a frame-off show build, the 1984 C10 headlights are one of the first things people notice on that flat, clean front end. The factory headlight is a Sealed Beam H6054 — a single large rectangular unit on each side that handles both low beam and high beam functions. These 200mm x 142mm sealed beams were standard across GM trucks of this era, and they are the single biggest lighting upgrade opportunity on the platform.
Because the H6054 is a sealed beam — with the bulb, reflector, and lens built as one piece — replacement means swapping the entire unit. That same design makes upgrading to 1984 Chevy C10 LED headlights completely straightforward. An LED sealed beam replacement matches the H6054 dimensions exactly and plugs into the original connector. No housing changes, no wiring modifications, and no trimming of the headlight bezels.
Best LED Headlight Upgrade for the 1984 C10
Square body C10 owners have an enormous aftermarket to draw from, and headlights are one of the easiest upgrades on the list. LED sealed beam replacements for the H6054 slot deliver a wide, well-defined beam pattern with bright white output that makes the original halogen glow look like a candle by comparison. On a truck with a tall, upright front end, the difference in road illumination is especially noticeable — you can actually see shoulders, lane markings, and obstacles well ahead of you.
Installation could not be simpler on these trucks. Remove the headlight bezel (four screws on most models), loosen the retaining ring, unplug the old sealed beam, and connect the LED unit. Each side takes about ten minutes. HID conversion housings are also available if you want to run a projector-style setup, though they require more involved installation. Every HID Nation kit ships free and comes with a lifetime warranty, so if you are building a square body and still running stock sealed beams, there is no reason to wait.
