Building up some LED tail lights (superbright at night)

You think these will be bright enough or do i need to add another ring??

PIC1: Just light on
PIC2: braking lights

What mcd LEDs you using mate?

should be more than enuf
those things are brighter than normal bulbs

looks cool, post more pics as u progress :)

8000 for the ordinary lights and 16000 for the outside "braking" ring. Doesn't look to bright on the photo but they are fecking bright close up.

Wait till I make the orange LED indicators... Should look good when i make the faceplate

You need to arrange them so they're like this (use Light Universe to view)

Already in the works :shifty: :shifty: :shifty: :shifty:

worked out costing and stuff .. will be about $30

Yeah, I had a go at this recently. Found that the trick is not how bright the lights are but how much area they cover. The wider apart they are the better the effect.

If'n you want, you have have a look at my tail light, got an integrated one now...

all LED etc, may give you an idea. Oh, when creating the turn signals, make sure the on-brake doesn't drown them out, some have said mine does :weep:

heres the one I made up, well designed while bored at work a while back, never got round to making it as needed to make a printed circuit board and that costs too much, oh and was going to use surface mount LEDs.

Why don't you use all the LEDs for both tail and brake.
Feed them through a suitable resistor to supply 20mA from the tail light supply.
And feed them 50mA from the Brake light supply.
Use a diode on each supply to isolate one from the other.
This will give you maximum number of LEDs for both modes,but with a brightness
differential

like my design, that has some driving lights then all on for brakes! But could be modified easy enough to do that

True could do that but i want them to pretty small when i do that...These are just for the race fairings I got so will do something more substancial if i change my ones.

For the STOP idea I will be doing something to what you suggest.
