I want a regular type light bulb - bayonet preferably - that, when turned on, flashes at regular intervals. Like, say, once a second.

 

Is there such a thing?

I know this is entirely unhelpful, but back when I was starting out as an electronics technician this was one of the first projects we had to do (actually we had to make a flip-flop and then interface it with 230V)

 

but thanks for the memory.

I had a flashing lamp that had a fluro starter in series with the lamp to make it cycle on and off.

mdooher, thanks for the link. It was a real bargain - reduced from $29.00 to $1.51!

 

Only one problem - discontinued line and out of stock 😥

 

richms: How fast was that cycle?

half to 2 seconds on/off, wasn't that predictable, and the starters only lasted a few months before locking off or on. It was a 60's decorative light that had 2 tiny pilot light style lamps in it, not sure if it would run much more than that.

 

Another option would be to get a wifi lightbulb that you can reflash with tasmota, and then use that to flash it when powered on. May have issues resetting to defaults if its powered up and down many times quickly in succession tho. The arlecs at bunnings are reportedly still easy to flash so long as you dont update them with the app to control them.

So why do you need a flashing bulb?

Actually you could just get one of the RGB wifi lights and set it to the flashing pattern you like and be done. So long as noone turns it off and on quickly 5 times it will just power up in the last mode flashing away.

That's a thought. Are the RGB bulbs 240v? Otherwise the rig would need a transformer. Starts to get complicated.

 

Squishy: A mate has an elderly relative living close by in a detached cottage. He's profoundly deaf so wouldn't hear distress calls, and his vision isn't 100% . He figured a flashing light in his house might be the easiest solution.

Mathew, thanks. What did you mean by '230V strobe.. or beacon'?

Could you adapt a flashing ringer? Dick Smith used to sell them to plug into 'phone line like an extension bell; I see some available on web.

My first reaction would be that flashing an incandescent, in other words repeatedly toggling it on and off, is going to lead to it remaining in the off state fairly quickly. However if you just want a visual alert than get a flashing red alarm light, something that's designed for the job and pretty much screams "alert!", e.g. this one.

Just set up one of my led lamps from Bunnings now and it's default reset state is to be flashing. So seems it does what you need out of the box with no further effort. If it's not flashing then to reset it is just 4 or 5 short power off and on sequences
