Got all the LED Lights all set up in the trunk and I found out stock light is 6volt. Really.

Does any know of a 6 volts to 12 volts converter?

so you installed 12v lights but the power source is 6v?

You sure about that? It's supposed to be a 211-2 bulb, which is a 12V. Maybe a previous owner put the wrong thing in?

I took the trunk light out and tested it on my voltmeter and got 6 volts.
Plug my LEDs light in and nothing.

Anyone has an ideal?

Yes sir.

All my last car has 12volts light so I was thinking this car would too.

You trunk light should be 12V. The replacement incandescent bulb is a Syvania 12V. If you change to LED then there should be change in voltage. It will just be a less wattage draw for the LED bulb. Have you tried hooking the volt meter up to the leads on the trunk? There is no step-down transformer that is installed in the car.

TriGuy

It should be. If you are only reading 6V at the source side of the circuit in the trunk, there has to be another problem somewhere in the wiring.

flip the led around.. LED's are polarity sensitive..

TriGuy

it could be the polarity when you plugged it in like punishmentcycle said, but what gets me is the voltage on the old bulb.

Here is a link to a direct replacement LED to the incandescent. Factory bulb is a 211...

In the link above they will operate in a range but the lower the voltage the less lumens it will produce.

I have a 12 Volt power supply I use to test everything with.
Plug the LEDs lights into the test power supply and bam the LED lights came one.

Can one of you guys run out and get a voltmeter on the trunk light?

TriGuy

I am at work so I can't at the current moment. You should be able to take your voltmeter to where the actual bulb plugs in and measure the voltage. How were you measuring voltage across the removed bulb if it was not plugged in?

If you are not getting atleast 12V across the leads located in the trunk then you either have a bad ground somewhere or a previous owner put some type of in-line resistor in there somewhere.

I removed the old light housing and cut the plug. Striped the wire and plug my voltmeter into the bare wire.

When I get home I'm going to test the interior lights and see what I come up with.

I've always wondered about that. Actually when I did the interior swap the trunk was the last one I did. It didn't work but I was aggrevated by then so I left it alone when it didn't work for me.

Just tested the inside light and there are 12 volts.
I'm going to wire in a relay kit to 12 volts and have the 6 volts trip the relay.

I would still look into the situation as to why the trunk light is only showing 6V....there might be some underlying reason that needs to be addressed.

I guess GM does not want the car to burn down with the HOT light. When I pulled my trunk light housing down it was melted.

TriGuy

iTrader: (1)

That is not the voltage causing that. That means too much power was in the housing meaning to large wattage bulb was put in. That creates resistance which will create heat. A 6V bulb can still melt the housing if the current resistance in the bulb is high enough.

There still to me seems to be something else going on in there, especially if you say the housing was melted.

That happened on our Buick. The replacement bulbs are all slightly larger in size than the OEM one was. So the bulb is too close to the plastic housing, which melts away some. It may be the wrong bulb was used in your car, or that some brand of it is slightly larger than the old one was. In 225k miles it has not caused any real problem, nor burned the car down.

It's hard to imagine GM stepping down the voltage, simply because that would cost money.

Can you go out to your car and test it with a voltmeter?
I want to see what Voltage your trunk light is.
