Review on Hella 9007 100/80W Twin Blister High Wattage Bulbs - Powerful and Reliable - 2 Pack, 12V by Mark Harrison

I bought this for a trip a friend was planning to take across the country over the next few months. They are definitely brighter than the standard Sylvania bulbs that were already in the car. A car with only one bulb for high and low beams with no fog lights seems to allow them to get the power they need from a standard wiring harness and relay. I see some recommending using them with heavier gauge wires and an upgraded relay, but in the case of the Ford Windstar they're fine so far. Time will tell durability, they seem to be hotter than stock.
