I have found these Eagle Lights LED headlights to be a great fit and look. Part number 4627B
They come with two vertical DRL strips on each side of the light. These replace the blue halo and wire in to that circuit nicely. They have high and low beam that are nice and bright, but not overly blinding when adjusted right. They come with a standard GM style 3 prong connector which the female ended needed to wire into the harness can be bought at most auto parts. They are totally seals and what is better about these is they are actually metric in size and fit in the stock housing perfect. You can even reuse the stock spring retainers to hold in place in the housing. I cut the circle piece at the end of the housing for the connector to pass through. Other then that they require no modification other then wiring to the stock harness to the female 3 prong plug. The DRL connect by a separate wire, but use the common ground of the lights.
