I found a Samsung 4 led ultrabrite strip that allegedly consumes 800 ma continuous. sounds high. Anyway, does anyone have a really simple circuit for pulsing this device. I am thinking of an array of 4 pulsing at the same time.

Let's see if I've interpreted your
description correctly. 4 leds (I preseume
white) to simply be pulsed in unison.

Are they wired in series? Is there a current
limiting resistor on the assembly (doubtful
at that current level). What's the application?
Landing light with attention-getting feature?

Apologies for not properly defining the issue ....the unit consists of four superbright LEds in a unit and is 12 v ready. So i want to take more than one of these units and create a flashing beacon light.
