The Kenworth 13-210 headlight bulb uses an H6054 size for both high beam and low beam applications. This replacement chart covers vehicle production spanning 1988 to 1989.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12 volts. It conforms to ANSI standards recognized in both the United States and Canada.
A sealed beam unit contains the filament, reflector, and lens fused into a single assembly. When the filament fails, the entire unit is replaced rather than an internal bulb.
The Kenworth 13-210 uses the H6054 for both high beam and low beam headlight positions across the 1988-1989 model years.
Because both beam functions share the same H6054 unit, the high and low beams are housed within a common sealed assembly rather than in separate housings with distinct bulb types.
