Post subject:  12V Auto LED Lights Voltages and other Technical Learnings.
I fitted a set of LED lights to my trailer.
Thinking that LED is less strain on the old wiring of my Vitara.
They were rated 10V to 30V and could be used on 12V or 24V applications.
At first I was very disappointed in poor light output
But investigations found only 8V at the cars indicators.
And they don't fire up till after 10Volts.
I solved that issue by fitting LED/SMD replacement globes to the Vitaras indicators,
and fitting an LED flasher can (Original was melted so lucky I replaced it).
I chose SMD's as they were listed as 8V to 14V.
Now the trailer lights are brilliant, and so are the Vits indicators.

I also fitted LED/SMD to reverse, Stop and tail.
The Stop tail only functioned on Brake lights, so am waiting for new ones in the mail.
I found 12V at the tail lights, so not a voltage issue.

If they fail, may look into "normal " LED replacement globes, or better quality.

This thread is for anything useful people learn about,
or want to learn about 12 Volt LED lighting.

I reckon the flasher was the cause of your low voltage, do you have a pic of the indicators running LED? there is a big variance in outputs so it would be good to keep track of ones that work well

I had something like this in the Vit for reverse, worked well with the way the bulb points straight out.

My flasher can had written on it max 4 globes.
My Vit has 4 per side plus trailer.
It wasn't a stock can, it was cabled tied to a bunch of wires.
Trailer lights improved vastly after fitting the new flasher can,
but improved more going to led globes on Vits indicators.

Don't want bright lights in reverse, have chosen softer light for them,
because I wanted trailer reverse lights brighter than cars.
Reason being, cars reverse lights lit up trailer, and was hard to see past trailer.
Have fitted camera onto trailer, which comes on with reverse.
I have a 2nd 10Watt cree reverse light, for when trailer not on.
Don't need the Stop/Tail Led's, but can't hurt.

Replacement stop/tails arrived. Good customer service.
Seller included the stamps for returning the failed bulbs..

Build quality is less than desirable, but you get what you pay for.
Plenty of light output.
Now I know it all is worth doing, it will get higher quality globes, if these ever fail.

They look stronger.
Mine were a bit flimsy.
I took out the stop/tails, weren't bright enough in daylight.
Indicators, parkers, and reverse ones are excellent, though.

Definitely whiter.
I'm finding the whiter light better for my reverse cam, too.

you will be better off with these
http://www.ebay.com.au/itm/2PCS-1156-50 ... ee5&_uhb=1

if you actually want something brighter then standard.

and i do doubt they are 50W they would melt if they actually were.

12x0.7 = 8.4w

That's a long way off 50w.

They could be referring to equivalent in incandescent. They just don't make that clear.
