Review on AUXITO H4 9003 LED Light Bulbs - 80W 16,000LM Mini Sized 6500K Xenon White Lamp, CanBus Ready, Beam Adjustable - Plug and Play Conversion Kit, Pack of 2 by Frank Ridl

I bought these because halogen lights are not suitable for my 4am commute. I've tried several different LEDs, but the fan doesn't fit into the case on most (the dust cover still doesn't fit though). Not only do they have a small fan, they also have a very small ballast. The beam pattern is slightly smaller than halogen but MUCH BRIGHTER and whiter. Worked great on my cruiser and sport bike. The high beams are a lot brighter, but to be honest they don't dip down onto the road as much. The fan is a little noisy when idling, but it's not audible at all when moving. Make sure the threads are skewed left/right, not up/down. They also have a really solid build quality and only time will tell how they hold up. But at the moment I can only recommend it for motorcycles.
