mass.
Im looking at buying some of these for a project. I planned on running them off of a sho-me arrow flasher. I was told that they will burn up quickly if I run them on 12 volts and the millenium cdi box powers them at a lower voltage, is this true ?


Also if they have manufacture dates of 2-03 what generation leds would they be ?


Thanks in advance for your help.

3v leds, 9v total for a card.


Second gen, i believe.


Life of the leds is reduced by powering with 12v but it will work.


Do you have a millennium?

I dont have a millenium. So using a resistor will fix the volt difference.
Thanks for the info.

This has been discussed before in another thread and the consensus was that they were 12 volt cards. To be absolutely sure with the specific year cards, call SoundOff tech support. If memory serves me correctly, I belive the person you are looking for is Gary. He deals with the 911 products. He'll advise you better than anyone else here.


Also, resistors limit current when placed in series with the product, not voltage. You'll have to create a voltage divider using two resistors and calculating the appropriate wattage ratings.
