How to disable the DRLs depends on the specific make, model, and year of vehicle you're working on. In some cases it's easy, in some cases it's almost impossible without causing problems. The preponderance of evidence is that DRLs, thoughtfully implemented, do reduce your risk of getting in a crash or hitting a pedestrian or bicyclist. North American regulations permit both good and bad implementations. If you are trying to disable the DRLs preparatory to "converting" your headlamps with an "HID kit", be advised such kits are dangerous and illegal in every single case.
