As I mentioned a few months ago, I have two of those annoying little lights like Subarus etc, one on each side of my headlight and they are all on during the day, at night I switch off the small lights as they cause too much general glare but during the day they increase my frontal visibility 100%+, the bulb things are cheap but the holders cost! I think I paid $80 at a car accessory shop, they've saved me from cagers pulling out on front of me a few times.
My theory is that headlights are too focused into a marrow beam for daylight use, these other lights have a 37 degree spread, (you can get different versions) and cars on side roads etc see them easier plus you not depending on one bulb which may have blown without you being aware it has![]()
