I do not speak your crazy earth moon language... WHo are these "chavs" of which you speak...?
No, don't worry... this is for a jokey, "deliberately naff" application. I am actually banned from driving this vehicle, -one of the very first stipulations of the Cheif Operating Officer when the vehicles were ordered. I in fact believe that I was the only employee (out of about 1,500) who was specifically named as being banned.
-So, armed with an evil sense of humour, the fact that the vehicle in question now bears graphics which identify it as "KITT", and the sting of a recent ban... I am planning to "naff it up" a bit.
perhaps a Burberry cap should be 'installed' in the vehicle, for the use of any approved drivers...
:wink:
Wayne,
I'll start a thread in the drawing board to see if there's any more input.

Let me make a semi-analog suggestion a bit different from those here so far...
How about a slow triwave of full-scale amplitude fed into a LM 3914 (whichever is the linear one) set up in dot mode to give the back and forth sweep (as Ed A. suggested),
AND
sum the slow full-scale triwave together with a high frequency (1 khz would do) triwave of maybe 2-4 step amplitude into the LM3914 input to PWM the drive to the LED clusters or light bulbs (to get the pre and post trailing light look) ?
You can chain the LM3914s IIRC to get 20 LEDs\lamps (or more if you want to go all out).
This can make a less precise, but purdy-looking, level meter, too. :green:

its funny, because not only did i make the exact same suggestion (worded a bit differently) including the modulation with a ramp osc. for afterglow, but Gus posted the same basic idea even earlier and i totally overlooked it when i made my post.
but yeah, the datasheet pretty much covers it. unless you want trailing only afterglow (not on both sides of the dot), in which case you have to cook up some way of inverting your modulating osc when you reach max and min on your main osc.
lights sure are pretty.

use that 1458 based triangle generator circuit. it works well. I used it to emulate the "breathing" power LED from a macintosh. Feed it into on of the LM39xxparts to get your LED drivers and voila!
Ok, it's now settled, now get to work.

as for a bipolar supply, I've seen some schematics of using an opamp to drive a half supply rail which you might be able to use as a ground if the current isn't too much..

why not hang some caps on the outputs of the lm39xx? Would the surge currents from charging these be too much? the LEDs have a known current and the capacitance can be added for a short glow.. but I'm almost sure that the glow was a combination of the filaments and the camera technology..

...I'm always surfing evilbay for vu meters/knobs/switches etc and this comes up every now and then when searching for meters...just funny i saw this thread about it!
...actually check his other auctions, all yer kit answers are there!!! Including this!!
