Cheers mate,
I've just bought the ones that Macca1411's got on his mate. They look pretty good to me, plus cheap!
Thats where your wrong had the same ones in mine and they failed with a 2 week period they loose the solder on the pins and just fall apart

I've had mine in 6 months now and still going strong.
You can't really say that buying the cheaper ones is a waste of money. I could buy the cheap ones from Hong Kong for 99p, inflate the price and sell them from the UK. It's easy enough to do, and some sellers are doing that.
The only way you can guarantee quality is to buy branded, but even then it's not 100%, the chances are they are made in the same factory as the cheap stuff.

not very bright at all! Don't think they came off ebay either!

I still think the ones you made with the huge panel of SMDs made the LED's look like they were meant to be there, which was cool
#20: Re: LED Numberplate Bulbs Author: Mikey2uk, Location: StevenagePosted: Thu Nov 03, 2011 9:21 am ---- You mean these
I can make them still if anyone is interested
#21: Re: LED Numberplate Bulbs Author: dumdum0910, Location: letchworthPosted: Thu Nov 03, 2011 9:26 am ---- you can buy them led number plate lights off ebay ..

Yeah they are about £40 to buy I can do them for £20 posted

Those ones are crap, you need the SMD LED.
This is the 5 SMD

I like those Mikey, no chance of someone not seeing your plate with those lit up

Last longer!!

So the cops can read your plate easier
#28: Re: LED Numberplate Bulbs Author: Debz, Location: Cardiff, South WalesPosted: Fri Nov 04, 2011 1:17 am ---- ive got the LED number plate bulbs, how long do they last roughly as they would always blow in my last car and only last a few months (it was a ford, no comments please haha) x
#29: Re: LED Numberplate Bulbs Author: ARRAN, Location: WiltshirePosted: Fri Nov 04, 2011 10:47 am ---- i bought these ones and there very bright

LED's ran within their 'normal' parameters typically last 50-100.000 hours - i.e. would likely outlive the car.
But I'd believe most of the cheap stuff is likely to run them harder (higher current through them which gives more light but shortens life).
Another problem is that (white) LED's operate at ~~3-3,6V depending on exact design, and the car supplies anywhere from about 11-14,5V. If you run a single LED off the cars supply, the difference in voltage must be handled somehow... Simplest and cheapest is a series resistor that at the approximate wanted current through the LED drops the difference between supply voltage and LED operating voltage across itself. Since the supply voltage is not fixed this is pretty much a 'get it close enough' thing anyway...
Also, in a small package like a wedge bulb, the resistor can't be big, and for the possible size, the heat generated in the resistor (function of voltage across it times current through it) becomes pretty significant and might cause the resistor to burn out or solder joints to fail long before the actual LED element fails.
