Hi all,
In order to have only one switch to turn on/off both headlight and taillight on an e-bike, I am trying to use the headlight as a turn on/off signal for the taillight.
The problem is that the headlight has push on - hold off electronic switch that I cannot replace with a DPST switch.
The headlight can work from 10 to 58V and at 48V draws:
2mA when off,
77mA day light,
195mA low beam,
640mA high beam.
The taillight requires 12V.
I can provide 48V for the headlight and 12V for the taillight.
My attempts to find a way to connect a relay in series with the headlight have failed. Solid-state relay LED's cannot handle 8x difference in current between day light and high beam, and I doubt a coil relay would handle that any better.
Any ideas would be appreciated.
