I use this one and it's great.
Dual Bulb Halogen Headlamp Kit
The Dual Bulb Halogen Headlamp features advanced reflector optics and separate bulbs for high and low beam functions. The euro-inspired projector beam styling combines a state-of-the-art look with a CAD designed faceted reflector bowl that is optimized for crisp patterns and light cut-off. The single upper bulb functions in low beam, and both upper and lower bulb operate in high beam. The low beam setting produces a wide curb-to-curb light pattern, and the high beam adds focused light down the center of the lane without compromising width. Kit includes housing, 55-watt low beam halogen lamp, 35-watt high beam halogen lamp and all necessary mounting hardware. Does not meet ECE regulations.
