The Norman Lamps 7225 is a 12V incandescent miniature bulb built around a dual-filament design that delivers 21W on the high-output filament and 4W on the low-output filament, all within a compact S-8 lamp shape measuring 2.00 inches in length and 1.00 inch in diameter. This dual-wattage incandescent configuration makes it well suited to applications requiring two distinct light levels from a single socket, such as combined stop and tail functions, side marker positions, and parking light circuits in automotive, marine, RV, trailer, and camper lighting systems.

The BAZ15D offset double-contact bayonet base provides a secure, correctly indexed connection in compatible lamp holders, with the physical offset preventing incorrect installation. The S-8 bulb shape keeps the overall footprint small enough for tight fixture cavities while the incandescent light source delivers the warm, consistent output characteristic of this lamp type. With a rated average life of 300 hours and full dimmability, this bulb is a reliable incandescent replacement for 12V dual-filament applications wherever the BAZ15D base is specified.

Norman Lamps offers the 7225 in single-piece quantities with a full case of 10 units available for higher-volume needs, making it a practical choice for service fleets, repair shops, and enthusiasts who require a dependable stock of miniature incandescent bulbs for 12V systems.
