I originally was planning on adding DRLs to my Honda Civic, until I realized they created added drain on the alternator, resulting in slightly reduced fuel economy (I know it's splitting hairs, but still
).
But what about DRLs that are solar powered or powered by a turbine?
An example would be these:
8 LEDs Car DRL Daytime Running Light Use Wind Power
I'm sure they could be done as a DIY project if someone had the know-how too.
Any thoughts? Effect on FE or drag?
