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 headlight use. Always check local laws to ensure compliance.

What is the advantage of a fanless design?

The fanless design improves reliability by removing a common point of failure. The SL2 bulb uses a copper-core circuit board and a thermally-optimized full-metal housing with integrated heatsink to manage heat without a fan.

What does 'direct plug-and-play replacement' mean?

Direct plug-and-play means the bulb is designed to fit directly into your existing fog light socket without modification. Simply remove the old bulb and plug in the new SL2 LED bulb.
