How to Control a 2 Terminal RGB LED


Just Got this 2 Terminal RGB LED......if I connect this 2 Terminal to a Analog Multimeter in R x 10,000 Resistance Range continously Red Light Flash, then Blue Light Flash then Green.

To make RED light only, I just need to momentary applied a power (0.1 sec)

To make Blue light only, I just need to momentary applied a little longer power (0.3 sec)

Have you guys, tried this 2 terminal RGB LED.....its nice for Battery Indicator for our RC Stuff.

There is No Manufacturer name, No device name......it look like just a regular 2 terminal Water Clear LED........I guess, it must be Pulse Wide Modulated to get the Color you want.

The Light Instensity is as bright as those Single Color LED such as Red, Blue and Green.......I guess its about 2000 MilliCandles.........its perfect, for Battery Indicator........Its so bright, that you can see it under a bright Sunlight.......this must be have same LED using on those HUGE Outdoor TV.

I just wonder some of you might have encounter this, and give me a link to its Website.

Thanks for asking.

Jeffs555: Thanks for the Links.......so ifs just an Tri-Color LED Flasher......the datasheet do not indicate how to control the Color......Too Bad.

I guess, I can force it to flash a certain color, by controlling the power input.....Just need to experiment the timing.
