Are these bulbs street legal?

In the USA, these LED bulbs are legal for fog light use only. They do not comply with DOT / FMVSS108 and are not street legal for headlights. Always check local laws regarding automotive lighting.

What is the advantage of a fanless design?

The fanless design of the SL2 LED bulb increases reliability by removing a common point of failure. The copper-core circuit board and metal housing efficiently dissipate heat, maintaining optimal performance without needing a fan.

What does 'optimized optical focus' mean?

The SL2 LED bulb is made to focus light from the same location as your original bulb. This preserves the focus and hotspot of the light beam, giving you added distance and visibility without added glare.
