electronic turn signal substitute?

Can you guys refresh my memory? Its been a while since I've bought anything like this. I'm looking for something that would be an electronic version of a turn signal relay. It needs to be adjustable so that I can set it to any time interval between 1 and 30 seconds. Like a turn signal it would be triggered, turn on, turn off, wait for how ever long you set it for, and then repeat the process. I'm sure DEI or PAC makes something like this. Can you direct me to part numbers? Thanks!

Look around for the people who sell sequential turn signal kits for cars. Try sequentialturnsignals.com, but there are other sites too. They might be able to point you in the right direction.

Also, not to sure if they'll do what you want, but some part numbers to look at are: DEI 528T, and PAC TR-7.

Thanks Chris! Can you verify that the DEI 528T will pulse on/off repeatedly? It needs to go on, off, on, off...ect at a pre-set interval. Thanks.

What are you putting this all in?  Whatever it is it sounds like an interesting project.

I am working on developing a system that vibrates the drivers seat when the radar detector goes off. Everything else is finished being developed, I just need a less mechanical way (than a relay and turn signal flasher) of pulsing the signal. I have several other projects in development too.

What kind of current will the vibrator pull?

Very little. Typically less than 2 amps, but final testing won't be until 4-6 weeks as I haven't decided on what to use for the 'pulsing' of the power.

I have some circuit boards here that have two "single turn" adjustment pots and onboard 2A relays.  The boards are about 2" x 2".  It wouldn't take much code to turn the pots in to ON and OFF time controllers and use the onboard relay to output 12vdc.  What kind of output do you have from the radar detector?

It's a negative trigger, but we could also tap off of the LED if needed.

Do they sell Velleman kits in the US? Part no 100 I think will give you trigger on/off repeated.  Costs about $8 here.

Here we are,Velleman do three kits,  K8015,  MK111 and VM141 all with adjustable start, pause, restart functions, all available in North America, I think they would be more suited than a 528t.  I'm sure sometime I've built and used an MK111 for this purpose.

Wow THANKS howie ll, those all look interesting! Appreciate the information

i also have a simple circuit design you could use if interested. it uses 2 NE555U IC's and two adjustable pots to control the timing of the pulses and the duration of each pulse.

That would be great Ckeeler! Please PM us or post the schematic

THANKS ckeeler. Appreciate the schematic :)
