Chevrolet Cavalier Seat Belt Warning Bulb Size

Additional Notes

• The seat belt warning bulb specifications for the Chevrolet Cavalier span the 1982-1994 model years, with three distinct bulb sizes appearing across that range: 161, 168, and 194.
• The 168 bulb is the most frequently specified across this range, covering the 1982-1993 model years with the exception of 1984.
• All three bulb sizes, 161, 168, and 194, conform to ANSI standards applicable in both the United States and Canada, and all share the T10 miniature wedge form factor operating on a 12-volt circuit.
• Despite sharing the same T10 wedge base and 12-volt rating, the three bulb types differ in wattage. The 161 draws 1W, the 194 draws 3.78W, and the 168 draws 4.9W, making them distinct in power consumption and light output.
• The 1984 Cavalier uses the 194 bulb for the seat belt warning light, which differs from the 168 bulb specified for the surrounding model years, indicating a fitment distinction specific to that year.
• The 1994 Cavalier uses the 161 bulb, which at 1W is the lowest-wattage option among the three types listed, setting it apart from the higher-wattage 168 used in the preceding model year.
• Because the 161, 168, and 194 bulbs share the T10 wedge base, physical installation across these types is possible, but their differing wattage values mean they are not electrically interchangeable without affecting the intended brightness of the seat belt warning indicator.
