since we don't have a electrical forum thought I would stick this here. need to know if bipolar electrolytic caps are still made and if not would a led block well enough that wouldn"t need a blocking diode on the ground side of a alternating flasher circuit?

Non-polarized caps are expensive. You can take two electrolytics and tie the positives together and that will give you the same results.

thanks guys the caps on the link are not bad on price till you figure in shipping. Don how would you figure the rating on the caps tied in that way there for a oscillator circuit .or would i be better off using blocking diodes?

If you took say two 100 mfd electrolytics and hooked them up this way, the net results would be 100 mfd. I have used them this way before, but would only use that method as a last resort. A blocking diode should keep your circuit from going negative and you could use any cap as a filter.
thanks Don think i'l try the blocking diode it will use less space what i'm making is a faux mars light with two leds .

will do Ray as of now the circuitry has been worked out .working on size reduction now .it uses two leds that i grind the package flat on one side and super glue together then insert into headlight hole leaving space for a clear lens.
