Subject:Running a 4.5v LED on 12v
From:John C...
Date:Thu, 27 Jan 2011 08:33:37 -0700

Hi All,

I have 4ea. 4.5v LED Wally head lamp lights that I would like to use
as porch lights on my Pop Top.

*http://tinyurl.com/4b6cgcj*
2 on each side of the top.
I would also like to run them independently at times.

Is there a way to modify the 12v's from the cars system
to run these?

Would I need a separate power supply?
Or is it possible to just integrate a resistor?

And to perplex the situation ;o)
Is there a 12v motion detector
that can be wired in.

I see Wally has a portable motion detector alarm,
for hotel door knobs.
Perhaps it could be modified to work
in conjunction with the switched lights as well?

Thanks
John
