Strobe works. Your body seat and bike frame will reduce the cooling it gets. The design has a poor thermal path from LED to light body, but strobe should ease the thermal load on the LED a lot and the electrical load on the driver quite a bit. Some of the resistors are marginal at full power apparently, so lower duty time should help. Flash is much more attention getting.
You might want to try it aimed down a bit so the hot center part of the beam only comes above the hood (and into the driver's eyes) of a following vehicle if they get too close (serves 'em right then, & should back 'em off). Guessing you have 2-300 lumens after losses to heat, reflector, glass and red filter. I have about the same spread about the same power but in four lights. At night, you light up road signs behind and that helps oncoming traffic see you, too.
Just charge the batteries in a fire proof situation.
