View Full Version : Can you wire 6 volt lights into a 12 volt system?

2012.02.28, 14:19 PM
I am looking at getting some spot / fog lamps. A lot of them are 6 volt. Is there anyway to get them to work with a 12 volt system? I did a google search, but they were just talking about 6 volt to 12 volt conversions.

you could find a 6-volt to 12-volt transformer...

if you only want them to work for a second or two. fog lamps should have replaceable bulbs. what lamps are you looking at?

Where are you finding 6v lights? Would it be possible to find a 12v replacement light that could be used in the housing?

I found this...

As an example:


They are probably 12 volt though.


I just want to know my options in case I end up with a couple 6 volt lights. I am going to be doing a lamp bar on front of the Mini. I would like to find 2 yellow / amber fogs and 2 spot lamps on the cheap. I am also thinking of running another large fog under the bumper. Lamp bar lights would be in the be in the 5.75" range. If I go with the under bumper fog, it would be in the be in the 6"+ range.

you can take those apart and change the bulbs to 12v. not 100% on that, but I am 99%. I just looked at one of those style lights that I have here and the yellow portion is a sealed beam. GE4415a is the pn for the 12v bulb. However, mine is 4.25"

no prob. :thumbup: if you want to get serious, you could use cessna taxi lights for the clear lights. 13v 250W. They are generally 5.25". Might need to work on the alternator/generator first though...

You laugh. I have them on one of my sciroccos. They are awesome.

Hmm, would you just need a uprated alternator and then relay them? Curious how you have them setup.

Both. I have each light relayed and a 90A alternator. Never had a problem. It was not possible to outdrive them. I think the longest period I had them illuminated was 45 minutes going to leavenworth.

Secondary and definitely not ideal idea is to wire the lamps in series. I would go with sourcing 12v lamps.
