Getting a light to work

[GeeMac]

On spec, I bought a 12 Volt auto trouble light bulb. It the same size as the standard 120 vac bulbs we've had since Edison.

I have 6 twelve volt batteries linked to produce twelve volts. The amperage will be high though. Is there something I should do to reduce the amperage before I connect the light bulb?

If the batteries are connected in parallel, and the bulb is rated for 12VDC then the bulb will be fine.  Keep in mind that a charging 12V battery bank will be at a higher voltage while being charged though.  Most items rated for automotive type use can handle that higher voltage.  The internal resistance in the bulb will hold the current down if the incandescent type bulb is operating within the voltage parameters for which it is rated.  Rich

 No you can go with it . I 'm a fan of using resistive devices  in series with the the charger  . Lights don't always fit in there though .

Your light will only draw the amps it requires. You needn't do anything additional.
