Interior Lights T15/921/912
Your vehicle’s interior and rear lighting should do more than barely glow—it should shine with confidence. Whether you're loading the trunk, stepping into your cabin, or backing out of a driveway at night, SEALIGHT T15/921/912 LED bulbs deliver powerful brightness and long-lasting clarity exactly where you need it.
T15, 921, and 912 bulbs are most commonly used in high-demand car interior lighting and rear lighting applications, including trunk lights, cargo area lighting, dome lights, and reverse lights. These bulbs are perfect for larger or deeper spaces where visibility is essential for convenience and safety.
Why Upgrade to SEALIGHT LEDs?
1. Intense Brightness, Perfect Clarity
SEALIGHT LEDs provide a clean, high-lumen white light that instantly enhances visibility. From deep trunk spaces to tight cabin corners, you’ll see everything clearly without harsh glare.
2. Long-Lasting Power — 50,000+ Hours
Built for endurance, these bulbs dramatically outlast halogens—lasting over 50,000 hours while maintaining consistent brightness and performance.
3. True 1:1 Halogen Replacement Fit
Our T15/921/912 bulbs are designed with precision to match the exact shape and light position of your original halogens. The result? A perfect fit in wedge-shaped sockets, with no need for modifications.
4. Plug & Play Installation — No Polarity Issues
No tools. No stress. Just plug in and go. SEALIGHT’s non-polarity design ensures the bulbs work regardless of how they’re inserted—meaning you’ll get it right the first time, every time.
5. 360° Illumination, Zero Shadows
Thanks to our hemispheric-lens technology, SEALIGHT T15 LEDs offer uniform 360-degree lighting, eliminating dark spots and delivering smooth, shadow-free brightness across your interior or rearview space.
6. Cool, Energy-Efficient Operation
These bulbs stay cool to the touch while drawing minimal power, helping preserve battery life and protect delicate interior materials from heat exposure.
