The Pontiac Silver Streak high beam and low beam headlight bulbs both utilize the H6006 size. The replacement chart covers 1950 to 1952 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6006 is the sole bulb type listed across all headlight positions for the Pontiac Silver Streak, covering model years 1950-1952.
The H6006 is a 5x7-inch rectangular sealed beam unit operating at 12 volts, conforming to ANSI standards recognized in both the United States and Canada.
A sealed beam unit integrates the filament, reflector, and lens into a single glass assembly, meaning the entire unit is replaced rather than an internal bulb.
The H6006 serves both the high beam and low beam headlight positions, indicating the Silver Streak used a dual-filament sealed beam design within one unit per side.
Because the high beam and low beam positions share the same H6006 specification across all three model years, no separate bulb type is required for each function.
The ANSI designation of the H6006 reflects a standardized form factor, meaning units from different manufacturers conforming to that standard are physically interchangeable.
