Daytime running lights
#2
it can be done. but you would have to rewire the postive lead to a relay and back to the ignition circut so when the igntion positive lead is dead (ie. when the car is shut off) it activates the relay to shut the head lights off..
obviously it sounds easier than it is

Has anyone done this before? If not, I'll get some electrical engineer majors from my school to help me out, and I can do a writeup.

I think due to the cheapness of oem bulbs, I'm going to make them the same brightness as regular lights.. I figure I turn them on when I'm driving anyway, so there's no net gain in bulb usage from this setup. My dad's Suburu works this way, but I also noticed that when the parking brake is engaged, the lights turn off. This might not be such a bad idea, I can think of a few times I want my car on but my lights off . This might take a little work, so if anyone has an idea on that matter, let me know. I expect to try this this weekend.

It seems like those things just don't last as long as regular bulbs do. One way that you might could try and stop this from happening (as fast) is using a resistor somewhere in the circuit (before the power gets to the light - this will restrict the bulb from running at it's full capacity during the day) that way it's a little dimmer than regular power and it may last longer, kinda like REAL daytime running lights. I don't know if you'd even want this seeing as though it would kinda defeat the purpose of NOT having to turn that little **** at night...lazy a$$ J/K. Oh yeah and when you're explaining this to your engineers you might want to remind them to take the resistance of the actual bulb into consideration when choosing what value resistor you might want to use...if you go this route

If you want, I can take some pics of it on my car, so you can see where it is located.

You know its funny that we have had DTRL's in our country in all cars since about 1991 and I had to look in the FSM to see how to disconnect mine and you guys want them.
The factory one though only operates at half brightness because both headlights are wired in series through the DTRL circuit so only about 6v at each light.
I just don't like them on when I am racing because of the load and I like to have control of what is on and whats not. I guess the best idea would be to just put a switch to control them so you can decide if you have DRTL's or not.
We have travelled to Fla a number of times over the last 10-15 years and everytime we would cross the border to the US during the daylight hours people would flash their lights at us because they think we forgot and left our headlights on.
