Hi,

Me and a friend are trying to fit a Blue Clifford LED as a part of a dummy alarm setup. We've bought an after market flashing alarm LED which doesn't look authentic and want to swap the LED at the end with a Clifford G5 blue one.

My friend thinks you can run 12v through the LED.

I've had alarms in the past and after calling the tech helpline they said I can replace the standard LED with a 5v one.

Can anyone shed some light on how much voltage a Clifford Blue led should be run at.

Thanks

If the led you wish to use does not have a flasher circuit built into it, it will not work and most likely blow at shortly after you connect 12v to it.

Buy a "flashing" led that suits your needs as I do not believe an out of the box clifford led (dei) will do this.

if you doubt my advice, connect it up yo 12v. If it flashes..you win. If it lights up real bright, and shortly burns out..you lose.

Then make your friend buy you a new one that works for your purpose.

I understand what you're saying, however, to make it clear we have bought a 12v flashing LED unit, but the LED does look like it's for a dummy deterrent:

What I want to do is replace the LED from that unit with a genuine Clifford G5 Blue LED:

and that's why I'm asking what sort of voltage is usually run through one of these G5 alarm LED's by the Clifford alarm brain as the LED cost me quite a bit.https://cgi.ebay.co.uk/CLIFFORD-G5-CAR-ALARM-BLUE-WARNING-LED-NEW_W0QQitemZ190039985658QQihZ009QQcategoryZ75329QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Ok got ya.

I will be able to reccomend a resistor value that should prolong the life of your clifford led to this flasher you have,

However I have nothing to work with.

If this clifford led came in a package let me know any specs at all that is on the label..I am mostly concerned with a current rating as that will allow me to use ohms law to determine the voltage.

If you have no specs, post the part number of the clifford led and I will find out the specs if possible for you.

Later

Hi thanks,

the flasher unit flashes the LED with 3.2v on and off.

The Clifford LED is a G5 Blue LED no specs on the pack but part no. is:

G4/G5 style Clifford BLUE LED w/retangular flush mount bezel. DEI P/N 909235.

Thanks,
M

I'm not sure if this is right or not but someone suggested Clifford Blue G5 LED's are rated at 2volts.

Can anyone confirm this?

Thanks

ok, I have to go to work now but when I get home I will recheck the post.

If no one has helped you by then I will look up the specs and post a solution.

best of luck

I would like to help but my sources don't have the specs and I don't want to be on the phone with DEI for 1/2 hour waiting for a tech.

The link you posted does not seem to work at all for me, I thought it might shed some light (pun intended)

Maybe you can go to that link and find the info.

The formula you use to determine the resistor value is ----- supply voltage - voltage of led/current of led

The supply voltage we know is 12v. The led is most likely 2 volt if its for a security system plug in type.

If we find out for sure what the voltage is and current draw (which they usually give with bulk or raw leds), we can do simple ohms law to determine the proper resistor value.

Good Luck.
