OK HERE GOES...

I'm looking for a amber LED (about 1W or less) that can switch as follows:

OFF
FLASH


Ideally the light can run on a hearing aid battery and one on each handle bar for turn signals. http://www.performancebike.com/shop/....cfm?sku=17651 This kind seens to only be seen from the back or side of the bike.

Any clue where to get for something like this with easy on-off buttons and better VIS??
