HID’s for the most part can grab your attention better for the purposes you stated. The “flashing” look can grab your attention, mostly for the in attentive drivers due to the fact that for the most part “flashing” =LEO which is usually kicking in their paranoia. Usually it’s followed by a quick tap of the brakes and a check of their speed. For me personally I ride with my high beams on during day light hours. I have come acrossed alot of bikes at night with HID’s and on a country back road, if the rider has his light mis aimed it can be a blinding situation. Especially if you just got through going about 30 mins with no other lights around but your own.
I say go for it, it seems like it will add a touch more to your own comfort which is what it really is all about for safety sake. Be sure to make sure you get the beam professionally aimed.
