Replacing DRLs with PIAA 540 Fog Lamps

[Mango]

This is from the PIAA site:

What is the difference between a fog light & a driving light?
Fog lights provide illumination forward of the vehicle that enhances visibility in fog, rain, snow, or dust. Fog lights are intended to be used in conjunction with standard headlamp low beams. Driving lights are mounted to provide illumination forward of the vehicle and intended to supplement the high beam of a standard headlamp system. It is not intended for use alone or with the low beam of a standard headlamp system.



I'm interested in the 540s for two reasons. First, the look with the lamp guards is very cool, IMO. Second, I'm trying to make the DRLs more useful at night, as a supplement to the factory low beams. Rarely do I use the high beams in city driving. The driving light version is likely to duplicate the factory low beam coverage; whereas, the fogs will fill in the gap closer to the vehicle and laterally. I hope. If I want extra illumination offroad, I can turn on my grill mounted offroad lights.

Also considering the Sylvania sealed beam HIDs which would give me simultaneous high and low beam capability on high beam setting. This, along with 540 DRLs and offroad lights would give me 4 light sources if needed each covering a different segment in front of me. (the offroad lights are effectively high beam floods) I've already ordered the fog lamp version so we'll see what happens.
