lighting off of 16v

jaytee50

can i safely connect my two 55w 12v wallmart fog lights to a 16v powersource (2 batteries)?

is there already a 12v output that can handle 110w on my 2002 cc ds IQ 48v?

here is what I would try
1 hook one to one battery check brightness
2 hook two in series to two batteries should be same brightness

if 1 and 2 are same brightness then

3 hook two in series to 3 batteries they will share the 24 volts @ 12 each and be brighter than above

You could also just run a dedicated 12v battery. That's what I decided to do. Hooked it up this week - works great!

shadowman

you might get away with 2 batteries but if you hook them to 3 say bye bye to your bulbs..................................

Tom Can you explain why the bulbs would blow

gornoman

The bulbs are 12v. Measure the voltage ANYWHERE in your proposed circuit and tell me what it is.

gaminde

remember I said series so two 12 volt bulbs in series is 1, 24 volt bulb so yes measure the voltage and that's correct.

example below is a motor coach that did this and its just an example


Headlight Wiring - 12-Volt Lights on a 24-Volt System

Early MCI coaches used 24 volt bulbs for all the exterior lights, including the headlamps. During the mid 1980's the 24 volt headlamps were replaced on the MC-9 coaches with 12 volt headlamps, beginning at unit 34901. By wiring the headlights in series, 12-volt lights will operate with a 24-volt system.
