Like the topic states I upgraded my headlights to h4 housings with halo.I wired the halos to my parking lamps and plugged in the headlights like normal. Turned them on the low beams are dim but when I turn the highs on they are bright as hell. Switch back to low beams they are dim and my bright indicator on dash is illuminated very dim? Turn highs on bright as can be. My jeep never did this till I put these upgrades in checked my fuses all good. What could this be need help. The headlight came with super white bulbs. Any info will help

IDK?... You may need to install a relay for them to work right. Or they are mis-wired.

You've either got a bad ground(s) or you may need to make additional ones.

Maybe the bulbs are too high wattage I think they are 65w/75w can that be it cause I think factory is 55w/65w. And how would I make more grounds just splice a new ground to harness

Yes, one on each side near the headlight plug.

Use 12 ga. wire.

Okay so I found out with my low beams on they are dim, well thats cause the high beams are on with the low beams. Wierd right but wait if u unplug my drivers headlamp the aftermarket one and plug in my old sealed beam I can see the the passenger side aftermarket one get brighter and its just the low beam filament on . If I unplug my old seal beam one that aftermarket bulb will go back to dim and both filament s are light up. Plug my old one back in headlamp works normal both in high or low beam. What is wrong here can the after market bulbs be defective. Oh and they are a 60/55 watt bulbs thats how its stamped on the bulb

Sounds to me that the lights are grounding through the high beam circuit.

So u think the bulbs are grounding out. Not my wiring cause I hooked up my factory sealed veams back in and everything works fine
