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 regulations, so they are not street legal for headlight use. Always check local laws to ensure compliance.

How does the fanless design affect performance?

The SL2 LED bulb uses a fanless design for increased reliability. It uses a copper-core circuit board and a thermally-optimized full-metal housing with an integrated heatsink to manage heat, maintaining maximum light output without needing a fan.

What is the advantage of the selective yellow color?

The selective yellow color is designed to improve visibility in poor weather conditions. Yellow light cuts through fog and snow better than white light, providing improved contrast and reduced glare.
