Strobe Light for plane?

[Brad kirk]

Anybody knows where to get those white strobe lights that ?€˜flashes?€™ a few seconds, that the size of 5 cent coin ?
Like to fit it on the wing tip on one of my nitro planes. I went to sim lim tower but they sells those colourful blinking LEDs good for the IFOs only.

Saw one RC F-16 turbine plane fitted with one powered by a 9v battery and it looked completely awesome. Anyone to advise ? Thanks
