Im not sure what one looks better, corner or headlights.
I do know you get a insurance discount for the corner lights being on  |
You should get a discount for DRL; whether they be signals or headlamps. My insurance agent noted that when I got the vehicle, also got the discount for the Vette, which uses signals, but not for the Jeep. (Farm Bureau)
As for why did they change, the magic word is GLOBAL. In some countries, the DRLs must be headlamps. So, a wiring change was made to make the DRLs all as common as possible. Don't ask me why the electrical guys didn't think of this in the beginning, since they knew the H3G was in the works.
As for a change, right now I can't say. The BCM controls the DRLs on my vehicle, via the signals bulbs. The turn signal lever and hazard switch signal the BCM that the flashers must be used, and the BCM then flashes the signals as required (flashers override the DRLs).
So far, the wiring has not been updated for the headlamp DRLs, but I have to assume the BCM is controlling these also, with the headlamp switch or light sensor overriding the DRLs. The BCM also controls the headlamps on the older style H3, via relays.
My guess is it can be done, but my guess is it might require a new BCM and/or a new wiring harness, or at the least a new BCM calibration.
I personally, prefer the signal bulbs as DRLs. In my opinion, they are easier to see, but that is probably a process of my old eyeballs, and certainly isn't based on anything else. Especially since I have seen some studies where the headlamps are more noticeable than the signals.
