    LED headlights/turn signal

    Got the headlights all wired up. Parking light wire turns on the white strip and turn signal blinks it amber.
    My issue is that the turn signal only work if the parking lights are on first, hazards also. The rear lights work fine. If I run the turn signal wire to both red and green wires on the headlight the indicators work but I have no parking indicators.
    And suggestions?

    I have the same situation with my truck; the solution I see right now, is to connect the tan wire to the ignition +12 and let the white strips be daytime running lights (DRLs), doesn't seem ;like it would hurt anything, might make driving safer

    There are no parking lights on the hot rod.
    You have 2 choices - DRL or no DRL.
    For no DRL, connect the red and green wires on the headlight to the turn signal wire in the harness.
    For DRL, Attach the red wire from the headlight to a switched +12V source (I ran a new wire to do this but you could repurpose the parking light wire). Attach the green wire only to the turn signal wire.

    I went with DRL. I used the tan wire to activate the white stripe. I connected it to the wiper wire since it's switched 12v and I don't have wipers.

    I wired up my headlights as suggested. Not using DRL. Currently the high beams are working whether the headlight switch is in the high beam or low be position. Ive tried playing with the dimmer too. that does nothing.

    Any advice?

    When you say headlight switch, so you mean the SPDT on-on switch, not the big fat turn-headlights-on pull-switch? The SPDT switch is what controls the high/low beam.

    I did find that my colors didn't match some forum posts, like the LED wires changed color at some point this year. So I worked out what went where with a 9V battery on the wires.

    Responded to another thread on this as well but Just a heads up to all..... it appears that they have changed colors again (see pic).

    Here's what I found using a 9V Battery (this is the wires coming from the headlight housing)
    Black-ground
    white - hi beam
    Red - lo beam
    small red - DRL
    small yellow - turn sig

    Attachment 137953

    to wire the DRL, attach the small red wire from the headlight housing to a switched +12v source (on my front harness I took the "tan parking light" and ran it to the switched 12v source.

    Then for signal lights simply attach the small yellow wire from the headlight housing to the "turn signal" wire from the front harness (on my front harness that is the blue on the right side; green on the left side)
