I have a 1973 F-100 Ranger XLT, and I just finished upgrading my lights with Steve Delanty’s instructions. Headlights are much brighter now. It got me to thinking, has anyone attempted to place a dinger inline for when a door is open and the headlights are on? I have issues with leaving the headlights on and draining batteries... Should this be too hard? Any ideas?
Thanks,

[font color=red size=3]It took me a while, but I might have something for you. I am assuming that the 'dinger' just has a power and ground (I'm not sure). This article explains the way a bosch style relay works, my plan is based on that.
Run a wire from the headlight relay (that is powered when lights are on) to the power wire of the 'dinger'. Now take a relay (like the above article) and hook the 'dinger' ground wire to #87a, and ground #30 to truck body. Run a switched power wire (power with key on) to #85 and ground #86.
So when lights are on, the 'dinger' is powered but not grounded. When key is on, the relay is energized, which breaks the ground circuit. Key off, relay closes, which connects the ground, thus grounding the 'dinger'. Have I lost ya yet?
Lights on, key on = 'dinger' powered, but no ground
Lights off, key on = 'dinger' not powered, no ground
Lights off, key off = 'dinger' not powered, but grounded
Lights on, key off = 'dinger' powered and grounded = *ding*
Haven't tried it, probably won't - I hate those noisy things! But it works in my head... if that makes a difference.;-)
JLS and Marty, I was thinking about using a horn relay to turn off my headlights when I turn off the key. My Volvo has this feature and it is really nice. Also never a dead battery because you forgot to turn off the lights. I really hate those dingers. I also did the brighter whites using the relays, and am happy with the results. I plan to take an ignition on hot wire run it through the relay to ground. This would close the relay circuit and provide hot to the light switch. The lights are hot all the time now anyway. Turn off the ignition switch the relay opens and the lights go off. If you need the lights you would need to turn on the ignition either on or acc to have power to the light switch. With an electronic ignition there will not be a problem with points burning in the ignition on position. I think this idea will would work so long as the relay serves as a load and does not act as a direct short to ground. Whatdayathink?

[font color=red size=3]It's the relay that controls the horn. It's like the bosch relays that you used for the lights. It works the same, just looks a little different. A bosch relay would work just as well.;-)
