I haven't really looked at myself coming, but I'm pretty sure it is very visible

there are about three miles of road in an older neighborhood between my house and my girlfriend's house. the trees are thick and there is only one street lamp per block. It is a really really dark street.

When going down that street using the Fenix light, it really lights up reflective road signs and reflectors on parked cars at the side of the road for at least a block or more ahead of me.

If those signs and reflectors are sending my light back to me that intensely, I'm pretty sure my light is visible at the side of the road ahead, and to cars entering the road. The bright spot on the road is bright, but there is enough light getting out to the side to be very visible to oncoming cars and cars entering traffic from side streets.
