The inane comments about using the headlight on-off switch are irrelevent !!
If you are fine using the headlight switch, then you have nothing to add or llearn from this thread.
DRL's only turn the headlights on (at reduced intensity). They do not turn on any of the rear lights, and most important to those who have in dash NAV/Entertainment systems, DRLs do not dim the display like turniing on the headlights. Some Nav units will go into night mode when the headlights are on (as opposed to DRL's). (Pleae don't hijack the thread with ways around this as they are varied by model all would require constant resetting of the in-dash units settings from night/day.)
Since I too like having my headlights on during the day, and the on/off operation to be automatic (especially the off), I am willing to spend $40 and a little time, so I have ordered two of the afore mentioned DRL kits for our smarts. What I expect after they are installed is, that anytime the engine is running the headlights only will be on at reduced intensity with no effect on anything else. I will keep the headlight switch in auto and would expect that when it gets dark all of the lights will come on to normal intensity and when it gets light it will revert back just to the reduced intensity headlights.
Please don't flame me, only expressing my opinion and plans...I will report the results as soon as I receive the kits.
