They are a great fit for the CB600F PC34. They are quite large (for dynamic LED turn signals), and they shine quite strongly, so they should be visible even in the daytime, although I would not risk placing them on the front of the motorcycle (I have them mounted on the rear). It's also worth buying a relay to support the LED turn signals, or modifying the existing one (my father modified my FR-3303 for about 76 flashes/min and it's perfect).
The turn signal itself is very good, it shines very well both day and night, however, very poor quality mounting rubbers that can "cut" after snagging on a small branch, but they can be repaired and both intensified with "droplet" or something similar and since glued, everything holds together
