Review on BEAMTECH H4 LED Bulb - High Lumens 12,000LM, 50W, Fanless Design, 9003 Halogen Replacement, 6500K Xenon White by Bryan Covington

Installs in approximately 3 months. They are much brighter than the stock halogens in my Subaru. The downside is that Subaru has a cover that covers the back to protect the bulbs and connectors, but with a radiator it no longer fits and the wires go through the grommet hole. The cover cannot be removed completely. So it just hangs open. Just like the male side of the 2 spade connectors on the headlights, they were actually too wide and I had to narrow them down to fit the connector on the car. It doesn't matter since you can't even see it when it's plugged in, but they obviously haven't tested Subaru specifically.
