Thanks homie.
I'm now working on brake lights that are dim untill you stop when they then come on full brightness. Like a real car......
After that I'll get the front headlights going as well. They will be dim in reverse and stop mode. Then full brightness when going fwd...

Midget, I got them from an aussie supplier. Just look online for SMD leds. That's Surface Mount LED's, much smaller than normal LED's. The yellow ones aren't that bright. I gotta up the voltage to about 5V so they shine a bit more. The DC-DC converter I'm using is one of the originals from a clone PCB, not very good. Driving 4 LEDS can suck a bit of current.......
Just wait till I finish the fully functional headlights and brake lights, now that's gonna look mad!

Sure, here it is.
This doensn't include the 3V supply, you need to source that as well.

These are rated at about 20-30 mcd which enough for this application. I'm experimenting with a 1.2V->5V dc-dc converter at the moment. The video shows the lights running on a 3V dc-dc converter...... These converters only work well for the LED circuit due to the current limitations.....

Brilliant stuff! I love it. BTW, where would such a circuit hook to a Zip? Great work.

I don't have a zipzap mate so I wouldn't know sorry. I got some old ZZ pcb's sessiz sent me, I'll have a look at them.
I've now got this running on a 5V source and the LED's are much brighter. Those DCDC converters are great!
Cheers,

old post, but blah or well...
anyways, for your brake lights, won't it be easier to wire it up to the car's rechargeable batteries? Since when your car is going, its going to drain the battery, and therefore, your lights will be dimmer, then, when you coast, which is partically like braking, the LEDs would be their brightest, simulating the brake lights.......
but.......if you're not going 2x cells, you can ignore this post....
