Spice has it almost right.
I have the spec sheet from the supplier:

I think it may be "surface charge" on the battery, but after 10 hours on the charger, I measure 14.2V on the battery, which quickly drops to 12.8 under a load of 780mA, then stays there for quite a while (haven't measured the time).
Odd thing about these LEDs, I have pulsed them with these specs:
On time (t1) is 0.00229 seconds.
Off time (t2) is 1.04 seconds.
Duty cycle is 0.22%.
Frequency is 0.96 Hz.
With no current limiter, just a high current transistor on the output of the 555. Ran the test for 48 hours continuous. No failures. Which calls into question the specs from the supplier.
Without a scope, I can only guess that the current has been exceeding 1A for that very short pulse time.
What I have installed on the trike:

At 100mA, the red LEDs without lenses can be seen in bright sunlight for several blocks (about 700 ft).
While testing the tail/brake circuit, there is a very noticeable difference between the 100mA and 340mA.
The reason I want to use only 1 switch for each brake lever is to reduce the fiddly adjustments for the switches.
