A bicycle can't mimic an automobile, or actually more appropriately a motorcycle UNLESS you can mount a 7 inch round or square headlight that puts out a minimum 1400 lumens with a low flat aim instead of a round patterned beam, and a 5 inch tail light that puts out a minimum of 400 lumens with reflective ability, then you would have to subscribe to using a steady rear light instead of flashing.

However that should tell you something, the bigger the head light lens the more noticeable you'll be and the easier for a motorist to ascertain distance to you, the largest currently that I'm aware of is the Phillips Saferide and the only one that uses a low flat beam like a motorcycle. And larger tail lights, but problem with larger tail lights is their wattage goes down due to using several LED's to save battery, however the couple I've seen do appear more noticeable further away then the small pin prick styles we use normally.

Also there is a problem with philosophy of how tail lights should operate, in Europe it's against the law for a bike to use flashing lights of any sort due to a German study that proved steady was safer...however, in N. America studies have shown that flashing is safer! Which is it? I don't think anyone knows for sure, but they have proven that flashing lights do garnish more attention, BUT, motorists have a more difficult time ascertaining their distance from them. This is why I run with my main light on steady and my bar end lights and helmet light on flash. Please don't ask me to prove my way is safer, I have no idea if it's safer, it's just what I do, I figure I'll try to hit on the both studies and maybe I'll be safer but I really don't have any way of knowing or proving I'm right.
