Led indicator circuit with constant on

01:09:40

Blinker circuit with a constant on switch. Tips for improvements?
The two leds will be at each end of a plexiglass stick

The circuit's operation looks pretty solid- good job on that. I didn't see anything component-wise that might fudge up the 555, so that's good too. (Certain things are fine for simulation but can be "iffy" at best on a real life build. As well as the other way around.) It sounds like you're gonna make a real one of these- that

*whoops! Anyway the only thing I would suggest for that is to use a single-pole double-throw switch (on-off-on). With that it's just one little switch to select between flashing and solid on. Oh, and this circuit's LEDs are running a little hot. If you build a real one, check the specs on the LEDs you're going to use, and match them up with the right current limiting resistor so they shine bright but don't burn out too early, or worse blow up! Always a good idea to build a test version on a breadboard with the components you plan to use on the real one.

Thank you! The plan is to make 4 of these (or 2, i'll find out) and place them in the headlight and taillight on my motorbike. The "blinking switch" will be the original indicator switch on the handlebar, and the constant switch i will mount someplace smart. I will check the led specs so they don't burn out.. Thank you for your help!

Oh, ok- I was thinking you were just making some little flashing wands or something. Customizing your bike is way cooler! About the switch- I agree it's probably best to have a master ON/OFF, and a separate switch for direction control. I hope it works out for you! Maybe later you could upgrade to sequencing indicators.. X^)

Sequencing indicators was an awesome idea. Later upgrade to a white hid-lightstip (plexiglass tube) with sequencing orange LED's. Or if i find out that the plexitube is not bright enough in daylight👌
