The only safe way to run HIDs on a 94-97 Integra is to retrofit TSX projectors, bulbs and ballasts into an OEM housing.
The OEM headlights have a very poor beam pattern when used with a plug-n-play kit. The design of the lens housing causes light to scatter into the eyes of oncoming drivers. You'll be wasting light that could otherwise be used on the road and you create a hazard for everyone else on the road.
The 98-01 headlights are better suited to a hid kit, but the cost required to update the rest of the front end is more than the cost of a good retrofit.
Return the halo headlights and price a pair of retrofits instead.
