I had both Photon Blasters (yellow lights on front) and P3 Lights (red lights on rear) installed on the Shadow, and I knew I would want them on the CTX as well. As I have said before, these increase your visibility tremendously because they have a microprocessor-controlled flicker that is unfortunately hard to capture on video. This flicker is barely perceptible but it is definitely noticed by drivers of other vehicles. There have been several occasions when I have seen a driver who was obviously distracted by a phone or other thing in their car who suddenly looked up and SAW me instead of pulling out in front of me. The flicker is most noticeable in your peripheral vision.
The red lights on the back (which I have mounted on either side of my license plate) act as running lights in parallel with the usual tail light. When you apply the brakes, these lights come on MUCH brighter and emit four quick flashes, then four longer ones before going to solid red. These lights are VERY bright and can be seen from a block away!
If you purchase the appropriate model (like I did), both the front and rear lights can flash in sync with the turn signals, adding even more visibility when making turns.
These are an amazing invention by Jerry Skene, an electronics engineer who is also an avid motorcyclist. I'd love to see these on a lot more bikes. I feel they are very reasonably priced for the amount of visibility they add to the bike, and Jerry's awesome technical support is impossible to beat!
