Need a 12V Signal light

[Free]

I need a LED light that will run directly off of 12v DC.

The light will be connected to a contact closure by two wires. When the contact closure is activated it will send 12v to the light to act as a signal for about 30 seconds and then shuts off.

I have been unable to find a simple light that can hook up this way. A flashing light would be even better preferably red.

I have looked for tail lights and bike lights but cant seem to find something that I am sure will run off of a 12V transformer with no modification.

Does anyone have any suggestions for someone who is electronically challenged? I usually buy all of my lights ready to go and am not knowledgeable enough to mess with resistors etc.

Thanks,
Phil

Phil;
You could just solder 6 -5mm red LEDs together in series-no resistor needed.
Do you have a "host" container picked out, or maybe a project box?

Good source for the superbright LEDs is either Hosfelt or BG Micro.

Thanks for the suggestion Doug. I was hoping to find a flashing bike light or something similar that would work but if I am unsuccessful I will follow your suggestion on the 5mm leds. I do not have a case picked out yet. I looked at the Hosfelt and BG Micro sites and they look good thanks.

Anyone else have any suggestions? Maybe something that didn't require soldering

I sold a 12V 3rd brake light off a Suburban to JRT, member 1908 about a month ago. Has 30 Red LED's in it. You may try contacting him. I don't know if he had any plans for it.

Could I just hook up something like this:

Third Brake Light

It sounds like it is plug and play. Hook up wrong and it just won't work. The transformer supplying my contact closure is 12V 500ma.

I found something else that might work. Half way down the page here:

The Led Light

It is a flex led board array that is 12v.

Boy, I keep searching and keep coming up with neat ideas

Free,
Does this have to be real bright or just a "pilot" light so you know that something else is on?

It doesn't have to be too bright because I will be using it in a darkened room. I do need to see it from about 20 feet away though, and it needs to draw my attention.

Free,
Sorry for the delay. I have a brand new 14 Volt Solico brand red flashing LED. Free for nothing. If you want to see a picture check out www.solico.com and go to "View Solico indicator lights .pdf catalog pages". Click on the first series (#18). It's the top one in the photo. White body, 6" wire leads, 5/16" hole, red raised lens. Just e-mail me your address if you want it.
Regards,
Kirk
