Hi,yes I am using Lazer tail light and having that for about 2 years now,I can't be more happy than before.it is very visible and reliable.
I recommend this one to everybody.
If it's brighter, it's better and safer. Those lines on the road don't look very bright though. I would prefer a really, really bright taillight combined w/ a brake light feature. That's long overdue on bikes, we all need a brake light too.
