I like the idea of daytime running lamps, even if they aren't mandatory. They make the car easier to see, even during the day, and you get a small discount on auto insurance. Apparently, some drivers are both blind & stupid, so we need to help them out by making ourselves more visible. I speak from experience. I got hit by a guy who ran a red light in broad daylight, claiming he never saw me. I was in an '06 Cavalier with no DTRL. I have insisted on them ever since. Don't care about the bulbs or the alternator. I just bought an '11 Caliber, but my understanding is that all Chrysler & Jeep vehicles today use the same wiring & light bulbs for fog lights. Since they were already available, I simply wired them to be used as DTRL. I am not a mechanic, and don't claim to be a genius, but I did this myself by simply disconnecting the existing wiring from the bulbs, and installing a $10.00 wiring harness. I wired this directly to the Ign/Acc fuse with a piggy-back connector (instead of to the battery). I connected the red wire that would normally have been connected to a switch, also to this same wire. Grounded the switch and the relay, and--Voila!--fog lights that come on whenever the ignition is on, which is exactly what I wanted. And the factory wiring & set-up is still intact if someone wants to unplug the fogs & plug them back into that. Mostly, I did that, just in case my idea didn't work and somehow interfered with the on-board computer. But so far, no problems. I am very hesitant to mess with the factory set-up (wiring, relays, lights, etc.), because that sometimes causes the computer to defibrillate or the car not to run. But in this case, everything seems fine. I'm sure there is someone out there that will find fault with my set-up, but for me, it works like a charm. Notified my insurance carrier, and got a small discount. I know the fogs are always on, even with the headlamps. Too bad. I have to look out for my own safety, since no one else does.
