    i bought some Projector/Halo headlights a while back and ever since i got them even after i turn the Head light switch to OFF they still Glow very Faintly but they do glow unless i disconnect my battery and if i dont disconnect it my battery is dead by morning.... I did follow the Directions that came with them..

    Ive even tried to rewire them and still NOTHING i love the lights a really dont want to have to switch back to the Ugly stock ones...... Anybody have any idea what the problem Could be?

    The ground wire and one of the power wires need to switched on the truck side of the harness, OR on the light side of the harness, the ground wires (plural) and one of the power wires need to be switched, as stated in the pm, i'll double check tonight which ones go where when i get home. I think the problem comes down to the fact that they are wired for a 9007 bulb, when we have (or rather you now that i'm running 3rd gen lights) a 9004 bulb. The Hi beam and low beam have a shared ground wire, with separate power wires. The 9004 and the 9007 bulbs share the same plug, however the plug is wired differently. I will snap some pics of my "corrected" lights tonight and put 'em up with the correct rewiring sequence for you, and anyone else that needs it because i know its a common problem with these lights. I found that out when i got them and started searching the interweb for my wtf question.

    alright, so i took a look and you can make all the mods on the light's harness. coming out of the harness there are 4 wires, one (red) that is the power for the high beam. one blue wire that is the power going to the low beam, and two black wires coming from the center post, one going to the low beam, ground, one going to the high beam, also ground. now, what you do is the following....

    Starting with the red high beam power wire. coming FROM the light, cut the wire and splice it into the blue low beam power wire, making it so that one wire runs power to both lights. now, take the ground from the hi beam and connect it the power wire for the hi beam. and that should fix it.

    what you did here is change the ground from the middle terminal to old low beam power cable, changed the low beam power to the center terminal. here is a diagram, like i said, the lights are wired for a 9007 bulb, and your truck has a 9004 bulb.

    I too have the halo projector and they look great and light the road well. The only wtf problem is the high beam indicator ( on the dash) stays on at all times. Will this wire wire change correct it?

    I believe that it does but you should probably wait for a Response from Loki or Codes They might know for Sure

    Yup, this will fix that. if your truck has stock fog lights they won't turn on either while your headlights are on because your truck reads that the high beam is on, even though they are not. And once you do this, the lights will be even brighter.

    @MvZiC MaN
    Did this fix your issue as well? and did your high beam indicator stay on as well?

    Headlight problems... Help! I also have the halo projector. The problem is the high beam indicator on the dash stays on all the time and lights are dim when all are on? Also fog lights stopped working after installing the halo projector lights?

    Worked for me!

    Thanks 'loki223', I did exactly as you described and my problem is resolved. The only diff is that before the Dim lights were on when I was on brights. Now that light inside the halo is off when on brights. But at least my bright light indicator is correct, and the brights are bright.

    Before...
    Dim - Halo On, Dim Light On, LEDs On, Running Light On, Dash Bright Indicator ON
    Bright - Halo On, Dim Light On, LEDs On, Running Light On, Brights On, Dash Bright Indicator ON

    After...
    Dim - Halo On, Dim Light On, LEDs On, Running Light On, Dash Bright Indicator OFF
    Bright - Halo On, Dim Light Off, LEDs On, Running Light On, Brights On, Dash Bright Indicator ON

    My lights were Spyder Halo Lights

    For some reason your Diagram doesn't show for me, so I just went by your description. Worked fine.
