A buddy of mine over here has been selling these flashing light units. it's a great quality product and has been selling like hotcakes over here! It is a very similar product to the yokomo flashing light unit, at half the price.
yokomo light unit: $45 US
It is initially intended for drifters in mind, but can be retrofitted to you off roaders out there too. before any further information is given out, just would like a hands up of who would be interested? thanks.
here's a teaser pic. front headlight unit or rear taillight units.
the unit itself has 7 different flash settings, but here's a vid of one the flash settings, displayed on his FD3S body.
