I drive a 2003 Mercury Sable Wagon, and replacing the old halogen bulbs with KATANA H4 Bulbs has made a huge difference. These bulbs are super bright; so much so that drivers often mistake my low beams for high beams! Installation was a breeze, and the bulbs fit perfectly. With a price of just $24.64, they offer excellent value for money.

Definitely recommend!
