Kauai1800 has asked me "Do you like them ?" I thought I give the response here in this thread.
The short answer is Yes, I like them as compared to no light at all. They are easy to mount, nicely shaped that fits RE, consume very little electricity so do not deplete battery.
I have seen some new cars with strips of white light, under the headlight, where foglights usually are. But I think white light is not as visible in sunlight because it is indistinguishable from the white day light.
Amber color is easier to see as it offers some contrast to white sunlight. So I would prefer an amber color LED module / pod, which will be better in light and dark. On the other hand mounting amber module right next to turn signal, which is also amber, may make it more difficult for onlooker to distinguish whether turn signal is on or not. So they would be better mounted onto leg guard, some distance away from turn signals.
The second aspect is the size. My pod has 6 LEDs. I would prefer a 12 to 18 LED module, a slightly bigger version if something in that size is available like a round 2" pod. Superbrightleds had a smaller amber 4 LED pod but not 6 LED in my size / design.
In short, an amber with few more LEDs would be ideal for the job, and a white with 6 LEDs is next best. One can put on these 6 LED pods to start with, and if they find better ones later on they can be easily replaced or even added on to them because all electric wires are in place.
