In my first Cherokee I put the Cibie' lights in with 55W low beam 100W high beam after several years of this everytime I hit the highs all of the lights, including dash, would go off. I blew the engine shortly after that so I never got it fixed. With the next Jeep I put the Hella's in with stock wattages. Both are a vast improvement over the stock lights but I prefer the Cibie' lights. Last weekend I put in the Painless H4 wiring harness and put the 55/100 bulbs back in. You could see the difference even with the stock wattage low beams over the stock wiring harness. Just a long way of saying Yes go with the H4 headlamps and a wiring harness with relays coming from the battery for full voltage to the lights.
