Almost all of those integrated lights are technically illegal. There is a requirement is for 9" separation between the two turn signals (16" on the front). The lens being clear is not an issue so long as the color of the light is red. There is also a requirement that all the signals be visible and obviou from 200' away in daylight, which is often an issue for a small housing containing LEDs that are trying to accomplish three things simultaneously.
Most places don't enforce these rules very much, but some do. I see lots of bikes with no turn signals at all around here, especially older "chopped" and highly-customized cruisers. We don't have state inspections here and LAPD could not possibly care less. But avoid Beverly Hills, certain sections of Orange County, and the a few of the other rich independent cities. They have plenty of time to ticket you for that and they will. (A fix-it ticket here isn't just a fine, it means it MUST be brought up to spec and inspected within 10 days or your registration is suspended.)
In states with regular inspections, these things can definitely be problems. A replacement tail light probably won't get much attention, but the lack of distinct turn signals often will.
Depends on your area. The rest of us can only guess what will or won't fly where you are.
