Bontrager Ion Pro RT/Flare RT Light Set. Expensive gift, but well appreciated.
Those HIGH settings are perfect to bright Texas sunlight. I use the strobe pattern during sunlight hours.
They have a lower power setting for the night either on or strobe. I use low intensity on at night — no need to blind traffic.
Neighbor rode his handcycle at night with high-intensity strobe. Oh, it would give me a headache when I passed the opposite direction. I had to come to a stop and let him pass. Not good.
For aircraft preflight, at night I have red flashlights. You can see fine; red cockpit lighting helped preserve night flying eyesight. On the bicycle, I want white lights, so others know I am approaching.
