I need some help here.
I have a small light I wish to use that is rated at 12V and
much greater than 500 mW.  

Can I get away with powering it be a 18V line at 500 mW?
Or could this possibly damage it from overheating or even
blow it?


If I can't hook it directly to the 18V line, can I use resistor
before the leads going to the light to reduce the voltage?
If so, what would the approximate value the resistors?

Thanks much.
