Show original supplier description
The Industrial TK-1003 is an incandescent miniature automotive bulb designed for standard performance in your vehicle's interior and exterior auxiliary lighting applications. It serves as a direct replacement for factory bulbs and is ideal for use in backup/reverse lights, trunk lights, dome lights, and more. This long-life version of the 1003 bulb is rated for extended service. Key specifications include a 12.8-volt operating voltage, 12-watt energy usage, a clear incandescent bulb finish, and a C-6 filament. It features a single contact bayonet (BA15s) base and a B-6 bulb shape, with a length of 1.75 inches and a diameter of 0.78 inches. The average rated life is 400 hours, offering twice the life of standard lamps. Installation is straightforward as it's a direct replacement requiring no modification. For optimal performance and longevity, it is recommended to replace bulbs in pairs to ensure equal brightness and color. When handling the bulb, it's crucial to avoid touching the glass with bare hands, as oils can reduce its lifespan; use gloves or a clean shop towel. The product comes with a 12-month warranty.
