erm not legal for use springs to mind, or you could do it properly and do it the way I made these plates about 5 years ago!!!
by using an edgelighting system you could illuminate a plate and there is no visible light to ruin the lines of the rear of the car.

or do it rpoperly as my bikes had and use a transmissive LCD this way with the right equipment its possible to have the LCD display your legal reg, in the legal font and a not so legal font, and then at the flick of a switch it changes to something else, ie a nice little logo or phrase, I then mounted an EL panel behind this, the EL was orange when unlit and lit up white, or can use a white looking one that illumiates blue, this was the one that really got me attention at shows etc..

white LEDs, looking for about 7000mcd ideally, could wire them in series ie 4off and that way less parts ie resistors etc required or just work out the current etc and use one dropper. these will be rather a narrow viewing angle, but thay are very bright, I use them as head lights in model cars, and in my warehouse at night can put a large circle of light on the wall 20+ metres away

just been sortin it, better get my solderin iron out cos its one hell of a lot of soldering
lol

yer i will be usin 3v ones mate, thinkin atm white ones just 2 c how it looks. not sure on quantity, how bright are yours?

No, I don't get them from work or anything but I've sold one or two on here. What sort of quantities and colours are you thinking of? I assume your going to be using something like a 3v resistor, in which case you'll need resistors too for 12v use. You can get 12v leds, but they are more expensive and don't illuminate so well.

how much 4 ur LED's m8

lol how many u got mate i would need a lot!
u get em from work or n e thin :)

just wondered what colour u want to see a demo of...............
Blue/White/Red/ or n e others?

If you want leds, I could sort you out. If your thinking of putting white leds in a rear plate though, expect to get pulled big time :o

well i am doin A level design tech.....my teach hates the idea, but am going to do it anyway, should have mine done in next couple of weeks or so if i can get hyper LED's and other stuff.......will keep posted

yep, think before you get anywhere with this one mate you will have to put up a picture off a prototype. as folks have nothing to compare it with !! have you actual seen something that inspired you to the idea ??
sure if you go ahead with your plan there may be a bit more off an interest in your idea .
good luck, keep us posted.
john.....

might be interested.. would have to see pics first though

anyone else interested....
i need to show that there are a few people interested in it for my project, so if you are please post :)
thanks
chris

so the letters light up mat, i am still looking into it, been looking at getting some Ultra Bright White LED's they look mint,
i will post pics up as soon as i finish my prototype :)
cheers,
chris

what do you mean by a led number plate?? you mean leds in the number plate light on the back to light it in a different colour?? or a surround like the neon surrounds you can get?? or a number plate made of leds so the letters light up??

Any more info ???

certainly might be interested mate, especially if they can be made switchable for say " track use " !! let me know if you have any more details such as design, price etc ??
cheers,
john.....

im interested

pics would be ideal mate...

wots wid face m8?

:rolleyes:

ok so thats one :)
i will do a demo with my plate and post up some pics,
chris

yea interested

btw i am pretty sure they are illigal just like all our other neon's and stuff

Thinking about making some LED number plates, just wondered if anyone on here would be interested?
not to sure about cost at the minute, just seeing if there is any interest,
chris
