Are these bulbs street legal?

In the USA, these LED bulbs are legal for fog light use only. They are not compliant with DOT / FMVSS108 and not street legal for headlights. Always check your local regulations to ensure compliance.

How does the internal fan affect bulb life?

The integrated top-mounted fan provides cooling, thermal management, and long-term reliability. Because the fan is sealed inside the housing, you don't have to worry about damage from dust or moisture, which extends the bulb's lifespan.

What is 'TST' LED technology?

TST stands for thermal separation technology. TST LEDs are designed with electrical connections on the top, which lowers thermal resistance. This allows the SL2 Pro to run at higher power levels than traditional LED bulbs while maintaining focus.
