    I have no problem with leaving the lights on all the time, so that's what I do, and I've had no ill effects to date. I documented what I did here, with steps: http://www.tmproductions.com/upgrade...hed-headlights . Unfortunately, I didn't think to take pictures at the time, so it's just text.

    +1. I also installed a relay long ago that turns the lights off with the key and on with the key provided the headlight switch is on. Same problem - kept forgetting to turn them off. It's a simple install.

    I think you might get DRLs by replacing the 2 existing high beam only bulbs with 2 high-low bulbs, then feed the 2 extra terminals through a relay triggered by the RPM Relay's Hot When Engine Rotating terminal.

    Optionally, you could add 2 resistors to adjust brilliance and/or a simple switch to turn them off...

    Or, just re-pin the low beam relay trigger (Blue/Gray) to the accessory relay. Much easier, less complicated.

    New car Auto headlights are ones that come on automatically at low light, surely, so they need some sort of light sensor.

    What you are asking for is "always on" which my car has, I think with the relay mod mentioned above. But I am not sure and was just surprised that my lights are always on

    Not that this is a pet peeve of mine, or anything
    I kinda like my LED light bars.

    But you can't scare me with a Geo Storm, I already drive a vehicle with a social stigma attached to it.

    Those aren't the ones I am talking about. Yours are factory fitted and aimed with the correct equipment.

    I mean the PepBoys special that are routinely fitted to trucks and jeeps and are approximately rated at "brightness of the sun". Often they are mounted mid-grille so it gets an uninterrupted path to your interior mirror.

    Hence the choice of the Storm, the antithesis of all things truck.

    I think you meant "Blue/Purple"...
    That would be good if you didn't mind the drain on the battery when you just wanted to run the radio or other accessory. I've used the override on my Silverado more than I would have thought because of the light itself.

    So, now I'm thinking I'd do that except triggering it with the RPM relay (87b, Yellow/Red) instead.

    ...Or, avoid that by connecting it to the RPM relay (87b, Yellow/Red) instead.
    (By Jove, I think we've got it;-)
    I'm not sure why you are insistent on tapping into the RPM relay. That circuit is over stressed enough as is. Even if it is just a signal to flip a relay.
    And no, I do mean take the blue/purple (blue/gray is for high beams) wire out of the low/dip beam relay socket, set it aside, and tie that now empty pin into the accessory relay...

    I would use the RPM relay because:

    But you said:

    And, blue/gray is not for the high beams -- There is no blue/gray -- Its trigger is US (Blue/Slate).
    [FWIW, G=Green. No Gray at all.]

    Anyway, it seems Shannon's question should be answered...
