SUMMARY

The discussion focuses on solutions for controlling motorcycle auxiliary lights using a flash-to-pass switch. A latching relay is recommended for maintaining power to the lights until the ignition is turned off. Alternatively, a triac can be used to achieve similar functionality, provided that an interrupt switch is included to control the power to the relay. Both methods ensure that the lights can be turned off when desired, depending on the ignition state.

PREREQUISITES
  • Understanding of latching relays and their operation
  • Familiarity with triacs and their applications in electronic circuits
  • Basic knowledge of motorcycle electrical systems
  • Experience with wiring and circuit design for automotive applications
NEXT STEPS
  • Research the specifications and installation of latching relays for motorcycle applications
  • Learn about triac circuits and their advantages in switching applications
  • Explore wiring techniques for integrating additional switches in motorcycle lighting systems
  • Investigate the impact of ignition-controlled circuits on motorcycle electrical performance
USEFUL FOR

Motorcycle enthusiasts, electrical engineers, and hobbyists looking to enhance their motorcycle lighting systems with reliable switching solutions.

New to the site, looking for a little help.
I'm trying to switch my motorcycle auxillary lights on and off using the flash to pass switch. I have a relay but only stays on when powered. Is there a switch I can put inline, or a switching relay that will work.
Thank you

You could use a latching relay, which would stay on while there is power. That might not be a problem (the lights would stay on until you turn off the ignition, probably), or if you want to power it off in the mean time then you'd need an additional switch to interrupt the power to the latching relay.

You could even use a triac, rather than a latching relay. It should achieve exactly the same result as the latching relay (compared with a setup without an interrupt switch to the coil - i.e. it would stay on, but should switch off with ignition off, assuming your lighting circuits are enabled by the ignition switch).

If the power you are drawing to light the light is not switched off with key off, then you need an additional switch in any case.
 
Thank you, I'll look into both ways.
